Thank. Ron pleasure to be here last time I read. Georgia Tech and the State game rich. Unfortunately and just at last ten decades ago. More than a decade ago also I mean a pleasure to be. Thanks for the invitation as I said Can you hear me in the back OK great. And I will kind of introduce to you in a minute it's very different take on any other university but I think we do a lot of things that are going to be a lot of interest to you I should Lonnie you that my seminar will consist of things that are applied than probably goes on here although many of you do quite a bit of Applied research as well as. Lot of kind of the basic details I wanted to kind of give you more of a flavor of different things we are doing than going very deep into just one area because I understand you know people in the room got a pretty wide areas of interest here so just how much we do kind of talk about. A little bit and I think that's a great idea. To have people including myself come from and so some of our you know in graduate school here or even undergrad might be interested in looking at San Diego or any other national lab for your future employment you can see fairly big we have the largest national lab. In the country we have about thirteen thousand people. About you know two point eight billion dollars and zero profit just to. Make sure that you understand our business model is just like yours. And we have if you look at kind of on the left side. Of. The kind of the miscellany as we call at Sandia So it's again very applied to. We have to be aligned with some very specific area that the country cares about and so the biggest one is nuclear weapons so there is a program in the country called stockpile stewardship for the most of you know we don't make any new nuclear weapons so that means we have to maintain the ones that were built decades ago and so that's a pretty big task and there's no testing allowed no real testing allowed So how do you make sure that they are in good shape and ready available if they need to use them hopefully never but also at the same time nothing goes wrong while they're not being used and unable to. Defense Systems and assessments think of that Department of Defense we do a lot of work out of op and our defense satellites and sensors and things like that. And as you climate an infrastructure can pretty much guess what that would be a lot of alternative energy research associated with climate change and the last one is. Pointer. So he should have asked for that earlier. Yeah there you go thank you. Yeah it's on. And I blame for this one day international homeland and national security where our job is to really. Prepare the country by doing and be against everything other than nuclear weapons that we should worry about. Everything else fits in there it's a pretty small part of Sandia and biology had a very broad easy to very small part of that ten percent roughly about a science program will be to the tune of thirty five million dollars per year and that's where I fit in we have. Kind of a big lead with him by a scientist by energy that is actually aligned with this group proxy here and then I was bio defense I lead this bio defense I. An emerging infectious disease Pod at Sandia because he had a lot of Engineers obviously despite made by a non chemical engineer because the chemical engineering and other engineering. And I'm not high enough to change this by shot. A lot lot of engineering that we hired just to tell you that even in computer science he doesn't have to have a computer science background we know a lot of I know a lot of chemical engineers who work in that area is really driven by by the need and not by the degree So again many if you send there should be an attractive place for your appointment or even an appointment did he such a start but he's such a staff I should also tell you we have a pretty strong internship program a paid internship we actually pay pretty well if you're a graduate student even a fancier graduate student will get paid for summer or full time internship at the rate of forty five thousand dollars per year and to whatever that will convert the hourly rate will be the rate that you will get. People really interested in a should look up on this idea employment Rep A We have a very good internship represents well. Let's kind of down to kind of a group that's again in the biology we have the bio defense I think really talked about it. You know that we need to play a big role here and one of the reasons national labs play a big role in both bio defense and by energy is that. If you when you look from a business perspective companies. Should have no interest in playing in this because there is no money to be made yet. For these two areas can be used later on for lots of other purposes but we're not there yet. You know it's not cost effective we know we are still doing a lot of research and development a lot of challenges need to be fixed before any of these alternative energy become competent if and that's kind of national labs enough. Come to play in our job is to take out those bottlenecks and biodefense it's just by definition there isn't much money to be made. It's not a surprise that there was no diagnostic F.D.A. approved diagnostics or vaccine for Ebola because you can just imagine how many vaccines a company would be able to sell in parts of the world where there is literally no money to buy them and then again it comes and then goes away and we don't know when the next time it will it will happen we do know there will be another infectious disease outbreak we just don't know what it is so it's a kind of a bad business model for companies to stockpile all these different vaccines for a lot of different things so that's the reason why we are only here because the kind of that's our mandate. The Canberra national security program. A lot of things for a lot of different a sponsor's. Highlighted is where I'm going to talk about detection and diagnostics develop them for about a fence about toxins but it's perfectly fine for us to move into other areas such as human health if they have a use in that other area so in fact and we are funded by Nestle the sponsors who are very familiar with it and I Department of Defense D.H. has internal money. So I'm going to start with a kind of. Give you examples of two diagnostic projects I would move quickly through these. Even though I wanted to bring this up even though this doesn't fit the directly in national security it's OK to be done here but a lot of the technology we were developing was very pertinent to diagnostics and so we put a kind of a good team together number of people in our streets are no longer a. Professor at Berkeley CHARLIE ROSE And so you should be extended at this time he was at Michigan but he's no longer at Michigan. You see some of the names you recognize from Michigan and I don't regard. Do a lot of work in microfluidics and girl here rise to really develop a portable device for rapid. Think of every time you go to a dentist's office most of the tests there are not invasive right other than obviously cleaning which is also fairly invasive. Kind of good can you actually take a little bit of saliva and while you're waiting for your teeth to be cleaned can the dentist run this device and get information on a disease that is confined to the real cavity or a systemic disease such as cardiovascular and you know things of that nature and obviously that's not a ride that is very noninvasive no one is taking your blood and so in theory the sampling kind of a deal in noninvasive settings. And the second part of that of course why you are you know everyone goes for dental cleaning at least once or twice or at least you should wear for dental cleaning once or twice a year and so the idea right that you can also get some other. Measures of your health at the same time. Because we don't go to a doctor most often especially in this country. And so the disease we chose at that time was pretty good on her disease so it's confined in. Mult it's a pretty big problem five to six billion and this is actually old two thousand and five data but it's also linked to many other systemic conditions especially hard disease and preterm delivery and women who have severe cases of put on disease and I'm going to raise that right now the top part is how we detect. Prey down to the disease and it's very invasive and it's mostly both symptomatic something is already wrong and that's why dentistry is doing a deeper dive to figure out what's going on other groups can we do earlier just look for saliva and look for markers that can catch the disease earlier and these markers will be if you look at kind of progressive left parietal disease we all have bacteria in our mouth but we don't all will develop some of us will do a lot to do with genetic predisposition by. Hygiene and but as the disease progresses you start to see different things being released into. Whole blood that could perhaps serve as markers for that disease so the blue everything in blue are kind of the potential biomarkers and you can see you know you know I want to put kind of very realistic what's sufficient and that is necessary and so you can see you have to get to a kind of third stage at that point kind of a confident diagnosis can be made. Deliver markers to now develop a kind of a portable device that can detect it so you look for a very simple. You know as a red it's just like any other. That you probably do in your lab to use a level and our body you only want need one because there is no solid fairly involved and you have the antigen which is some other markers that you might be looking for if you combine the two you and if there is any antigen in your sample you will get to product a level and ID that has captured the Andes and the second one which is excess the agent and you just separate them because they're going to be different in their charge to mask characters tick so you just use electrophoresis to separate them out you should see two peaks and that issue of those two peaks will tell you how much of the light is present of course you have to build a calibration curve so that you get some quantitative idea of how much and I did present in the sample so I'm going to rock through that very quickly kind of a chip that does this. So it was a very simple chip really feature is that we make a membrane by photo and we make a membrane here the red spot that's kind of the reactor that's where most of the X. and will happen most of the amino acid will take place and it actually gives a lot of advantages to using it this way so it's a kind of homogeneous interactive but we're using a membrane so it's a kind of. Mix of genius and homogeneous asses and. This is the real chip on the right side you can see the size of the first step is we take the entire body which is eighty years into a little bit and now you can see that advantage of this memory and its memory. So that it's very small things such as salt and water molecule can go through but will go through so they will stack up to memory and literally of any little bit about two hundred fifty or even five fragment or sci fi none of them will ever go through so they really start right here in the second step and you'll be in your sample which will be the saliva which will have the right so let's see whether this movie plays. And so you can see in this case we're just using a fluorescent label protein to make the movie you know obviously. It will not be labeled from saliva and you can see it's very nicely stacks up against this membrane Now two things are happening you have captured your sample exactly were at the same place where you antibodies are so you get very nice mixing going on and in fact you get local concentration is much higher than the concentration in the same time so you actually get an extra in fact if you do the principle you're basically shifted it will be in constant to the right so you actually get much by hiding binding constant of course both you know OK on and off but if you do the separation quickly enough before everything I disassociated you actually can do Texans are very very high level or very sensitively. Take a step is you let it incubate for one minute that's all we take because it's locally concentrated there's no limitation from diffusion really so that can happen much much faster and then that one minute is really. The field and let it go this way and it comes up as a very nice band and then the last one you can. As you travel to down the street. You really start separating So the first really just excess die so that we use that as an intern a standard and then these are the two peaks. Not separated in this movie but this entire scale is hundred micron So that's right you know that kind of mushed together they're actually fairly well separated and you do that at very different kinds of distance of and light and you get generated. And against that calibration curve you will compare your sample and so the total time frame if you have been kind of watching has been a few minutes I mean even the separation gets done in about three minutes because the scales are so small for for capturing them for separating them out and that's where the advantage of time comes in by scaling down the demands on you really made everything much faster and here is a kind of just kind of quickly through that we have taken. Kind of the peak and you know kind of generated a calibration curve with non standard and then we actually put some patient samples here you know the patient from pretty down to disease came from University of Michigan dental school and you can see that I'm right on this curve and we can figure out you know what the content is of this particular. Market which is M.P. eight it's one of the and. The concentration goes up if you start having bigger it isn't and. You know obviously you know probably a lot of papers. And we had an integrated device with this. But there was also a lesson learned and I was going to share that since I talk about Applied Research So this is all great for publication and things like that so we then approached a lot of companies hey this is so cool you must be interested never just learned that. One page for Peter insurance companies don't pay unless it's really bad and they have so hence they have no imperative to detect it early because then it's really bad news for them they have to start paying even earlier. And so they just ignored it and so that's number one so don't start developing technology unless you know that there is a need for it. And the second I had read this is much interesting Rand. Of the doctors are not happy with dentist. Doing diagnosis of systemic disease because that's their turf and I know I'm being recorded. But you know but it's a very important lesson you know maybe it's not fair and maybe to Shouldn't be that way but it is that way and you have to be really careful. The dentist would love to detect every disease you ever have right cardiovascular and things like that but then doctors are not very happy so now you go to a clinical trial it becomes very very complicated as to who you partner and happening with both of them at the same time is not that practical. And because both of them are individually happy to work with me but not so happy to work with each other and these are kind of the lesson learned the alternatives to the enemies that I forget put on disease there's a lot of other things that should be useful to other fields as well because if you can do put it on television marker like M. and B. eight is just like any other protein the problem of this is a little four document absolutely great in the lab and great in running. Samples that are fairly clean not so good for doing serum and blood especially not so good for saliva either because it could be a lot of various sums in terms of you know what the protein county's what the total blood count is and that actually ends of shifting your peaks and so it wasn't a very practical devise. That we learned when we started applying this to other applications so even though it was very exciting we were very excited and didn't go anywhere and so that's kind of you know on the breast twenty six or seven years of my you know heart of my career working on it Lesson learned and lesson learned that it's never too early to think about. What the technology can do if that is hundred percent successful problem solving and I tried to teach this earlier to people who come to us and the unfortunate Unfortunately there wasn't anyone else telling me when I joined so. Let's move on to a spin direction you can see how simpler this device is this is a lab on a desk again not a platform that we invented centrifugal microfluidics has been around for quite some time except that this was invented because we had a problem. This made perfect sense to develop and get to you in a minute as to why we have lots of patents and just to give you the news. For the last light had been commercialized by six companies including one a startup from a couple of staff members on a postcard that reported to me left to start their own company and they are going after neonatal disease and other other diseases and in addition to that company there are other five companies that have licensed this technology. So I want to acknowledge most of the work actually was done by people listed here. SCHAFFNER post-doc and great summer. Staff member who left to start their own company and the concept of it is very simple and shown here in the bottom correct transfer to a disk or disk into this device and then run it we wanted it to be a plug and play you know centrifugal microfluidics it sounds very much like CD player actually that's where the idea came to people. And number of people have been pioneers in this area. All the chemistry is in the disk so it's just like a CD player the magic is in the days player is just a passive reader which will read any particular disk and you have to basically make sure that the disc is encoded so that the player knows what it's reading. You know you really need to add to twenty Michael lead of samples and then. The reason is that you can do her blood directly into this device that is no reason for the blood collection you could do that if you have access to that that can be done as well but our garage takes a life or her blood directly by either spitting for saliva or by pin prick for her blood put it directly in the reader and that should be enough to run this disc and you know the time and things like that the disk a single use obviously you know you you know that's where it's unlikely that you can use multiple times but you can do up as many as sixty four at the same time. You know based on amino acids just like the last one except we use beads here so you have beads. That have antibody attached to them that's your ears and we also have a little bit about it so that's your secondary agent. Typically quantum dot because they're much more stable and we add them together and here is recreate the novelty is really just going to center field microfluidics by expanding the discrete actually prepared density media so this is like analytical center figures and for those of you where you have done certificates and at larger scale so and then we pick the beads so that they are the only things heavy enough to go through the density media everything else everything which is very close to one point in a specific centrally stage on top you know because we can put we can make it close to one point two five nothing in your blood or any sample will go through this top to have done my sample prep while you're doing that you know asses beachside silica to point to much much heavier specific gravity they're going through but by the time the growth through they have actually captured the and the light as well as the label antibodies so you're kind of formed a sandwich which is for us and and and but the only build and her body again it's a protein specific gravity very close to water straight on top. So you have done your sample prep and you are separate sort of bound from on bound in one step and then you have multiple antibodies so there you go again another constant is an effect that's going on each beat captures many many and like molecules at the same time and then you have thousands of beats so you don't have to worry about sort of leaching and things like that you can read this for a second or two seconds and don't have to worry about for the bleaching because you have plenty of concentration here to read. It really well again I wanted to point out that there are many. Devices out there the Center for Grayson out is very different because none of them really use that density media that we put in and that's. The patents and many of those patents have been issued so companies are happy to license this from us. That's another important thing you can't just do it for the first time you have to let everyone know that you have done it for the first time by falling apart and probably get some doesn't really count when it comes to a commercialization and so we have. Got to do that very aggressive about protecting our IP because if you don't IP. Minimal chance of anything being commercialized because that's what going to protect the company from using your technology and protect it from anyone else copying it here is an example we were talking to I'm going back to my bio defense kind of. That. It's a big problem. You know you get white powder samples you're probably already of that how do you know what toxin is in there it's the most. You know it's the most pox and some substance known to man I mean literally a few nanograms can kill you and so you detect insensitivity has to be very very high to detect it at eleven concentrations and here I show you that we're detecting it and I'll show you the sensitivity in the next slide but you can see we can mix of course talks and is not found in all these food in a person. Kind of you know became very ambitious and basically took everything that you could spike them with toxin and basically sure that we can detect it in pretty much anything you can think of obviously it's very tough to get canned meat and peanut butter so there was some of. That we had to do before. The second part I also want to tell you this is another important thing that you are developing for the first time or whatever method you always have to show the community especially the biological or clinical community that it actually matches the threat being used now that's the only way you can make them confident that this actually works so we actually brought commercial actually is not a commercial. Developed by U.S.D.A. because they have the mandate to test food for contamination with botulinum toxin and blind and you know when we do very very well compared to U.S.D.A. approved. Here to when I was going to show you for the sensitivity so here is the grill a standard for botulinum toxin on the right side beyond ten people and it's a mile marker staffed mostly by asset so literally you take your sample and you feed it to these poor mice and you see what happens to them and they have to sacrifice them no matter what happens to them so even if the toxin you have to sacrifice them at the end of the day and here is kind of the result you get You see we don't run that many concentrations for mice because you don't want to kill that many mice. You know you're a you're a limit of detection is somewhere between two to ten although we couldn't detect any ten sometimes you could it also depends on the mice there is another one called. West so literally if you give them toxin to my eyes since it binds to neuron. Turn into a dumbbell. It's not a good picture to visualize but that's what happens to them the wrist area becomes really ten and that is very is. Pacific for a bottle and I'm talking to people can use that as a subjective test as well but needless to say we can we do much much better because we are really even the last concentrates on. It. You know like hundred times lower effectively even if you take over ten factor. We are ten times better than a mouse by Lassie so that hundred years are is much much cheaper and second you are not sacrificing my so we are really hoping that I said like this can replace the most testing for many of the toxins that get gets done. It's not limited to bad defense toxins only how mean we can do. Sixty five in because if it's any meaning we also want to see whether this is a genetic amino acid platform and it really is. You know again I only talk about bad this was actually published in. Chemistry just recently we can do multiple toxins at the same time and so here is kind of an example where we have it around Rice in protective and isn't she. On the on the same disk and we do and I'm going to be compared with whenever we get a chance and we can either meet the sensitivity that is offered by the. Times of the actually do better. So here's a question since there are lots of students here. To scale the wrong to go wrong and so here is an example showing you that. You get a kind of like this and so maybe at the end of the seminar if anyone has an insight as to why this happened let me know so he what's going on is I have to concentrate on just think of. And here is your X. axis which has an increasing amount of you go from left to right and left is that it's coming from binding and you get a kind of like this so I would like to know why do you get a kind of like that obviously is the problem because if you get a kind of like this and if you look at France you don't know. The contents only see one or two and there's a huge difference because he too might kill you when might we just OK so anyway this is a kind of small Christian if you don't have answers that's OK I'll tell you anyway and this is real and I will tell you right this happens. We can answer since it's a simple after you don't have to be limited to you know assets any place where there is affinity binding you can use it and so we shorted for. For Food borne or water borne illnesses where you don't have to detect very. Little concentration and if you especially if you concentrate them. Actually works quite well. I think I'm going to skip through this fairly quickly to kind of get to the last part. I already showed you this it's compatible with blood in fact actually you can see the red blood cells I don't know whether that's visible to you it's pretty nice on my screen actually you can see it spect right on top of the density media so your center figures and you can actually use it for sorting or not but self-righteousness and if you would like to. And he's going to tell the difference between red blood cells and white blood cells by the way and if you use anti-bodies you can subtract an eight right blood cells and it's a very simple platform very easy to adopt in your labs if you're interested. Very simple two pieces of plastic stuck together by. Double sided tape. And so we take a little cut the tape and that defines your channels so all the channels you see basically you know so you can pick any thickness of the paper you want to that gives you the depth of your disk and then how right you cut it defines how much total volume you'll have in there and then literally read. On the top part of. Just with any C.N.C. machine and then we stick them together and you have your. Of course if you are scaling it up you most likely go to injection molding or some other other method which is more scalable right I mean this is something that person to do. Or do you see it and then stick them together but even in our hands we can make hundreds of these in a day. And a little cutter you can buy for about fifteen thousand dollars and then also make them someone just told me that they made it by three D. printing so that's a possibility too not an expert in three D. printing so I don't know what they used a very simple disk is less than two dollars even with the anti-bodies the cost is so that for honesty the cost is not determined by the plastic because of course plastic is cheap cheap cost is going to be determined by the cost of fuel use and which of the anti-bodies and labeling them how much labor is involved devise is very very simple like it's much simpler than a CD player so in theory it should be less than fifty dollars However you know. Actually a person of the CD player they are only interested in making something like this if I order one hundred thousand which obviously is not the case so in our hands it's cost about two thousand dollars to make it that's just the cost of the material if you include labor. It's much much higher. OK so if the question kind of move to the last one is. Kind of my preferred IT platform for synthetic biology probably different. Bio Energy and I will introduce that. In a minute. Synthetic biology is a fancy term it's just. Like engineering or genetic engineering by other name. And here what I'm thinking about is putting entire Patrese. And moving it into equal least at one time. And kind of get to that sort of. In a microphone platform most of the record has been by a number of stocks and research a staffer J.B. Steve she and Phil actually have done most of the work and then Peter and others have helped as needed just is no longer our job left for a start up company. I think I don't know how many of you are familiar with Byron A Z There are only a couple of ways to do bio energy the big areas are. So kind of biomass you know Conestoga are not corn in the world include corner here and the second is. That they're starting and this is more the plant like trees and grass and things like that. And then you have multiple steps involved you have to first break down the biomass kind of pretreatment very chemical engineering typically do it combined chemical or heat and genetic then to release the senators and then you have to bring in because that's the only way we know how to do this very efficiently that break down those cellulose to simple sugar which then can be used by microbes. To make biofuels Pamela's here obviously. And I were together have question about synthetic biology addressed to her because you know that scene or that much more than I do. And again kind of introduction to that might be also of interest to you it's. Kind of introducing that in the beginning it's a multilevel partnership so this is funded by do you eat and do you fund I think it might be the only agency that fund things this big anymore especially given given and I just lack of interest in front of the example of. A little limb is twenty five million dollars per year we got another thirty million to buy equipment right at the big. And funded for five years at a time and we are in the second renewal right now and we're hoping that we'll get another third in two years from now it has seven partners for National University and one foundation kind of there are listed here Lawrence Berkeley is the lead lab. Another chemical engineer from U.C. Berkeley Lawrence Berkeley he's the lead Sandi I was part of it. For a lot of plant biology and we have Carnegie science from kind of the Stanford campus and Pacific Northwest National Lab. For been isms feedstocks deconstructs and fuels and cross-country technologies so I cross-cutting technologies out where our goal is to develop technology to meet the needs of the other three divisions. And. That kind of brings me to kind of ride microfluidics an idea. You know really regular fairly applied project screening becomes very very important because even few percent optimizing compared to existing method can mean a lot in terms of your total cost on a scale that you are shooting for and one way to do that is to screen lots of different conditions just to find that best condition. That the you need to have and that can be for optimizing your enzyme cocktails. Even a concentration difference of ten percent can make and I'm talking ten percent cheaper or more depending on exactly what particular protein you're talking about. Kind of this Internet biology area where we are trying to put cloned bunch of pathways. Back to a yeast or a fungus and let me just give you an example of this scale so suppose you have a partly of six genes that you wanted to put in equal to make beautiful or ethanol. Not that interested in ethanol anymore but it's a beauty. And suppose that Teller two hundred species very easy to get you can just mutate a couple of time into acids and can get to ten alternatives or they can come from different organisms because many different organisms have very similar enzymes. So if you want to do an entire communism you have to do tend to the six experiments so that's a million experiment. Almost impossible to do in a micro tighter plate because that is our standard high throughput platform available. And just think how many micro Tiger played you'll have to run it's almost impossible to do it manually of course you can buy it really bad by the now you're talking about millions of dollars to buy the robot and then multiple people just babies that are about because they don't work as advertised that's all been there has kind of you know and we haven't gotten there yet can we should everything down to take advantage of it scaling down to do larger number number of reactions in a smaller footprint and. Hopefully also make it faster and the most important by automating it you take out the human error from that and the last one is that if you scale down. There is significant cost saving and that's actually the bottleneck right now people can do a million experiments for synthetic biology part to synthesize D.N.A. for those million million experiments would be cost prohibitive we would just not do it because it could be in the orders of hundreds of thousands of dollars and so the cost of the biggest driver you know bring it down by a factor of hundred and I do write that just use this droplets these are water droplets suspended in a while as discrete reacts and chamber just like your micro tractor Well if separated by plastic he would have separated by oil. We were not again not the first one to think of this so here are some groups that have done very nice work in this area. I think you started it in your city of Chicago. David. Came from White's lab. And there are many others just just to give you an example of this. Attention from a lot of people this is a format where droplets always keep moving so we kind of call it droplets in channelled operating flow or analog. Microfluidics and I know. That using something like this we also used it in the beginning to do lots of friends I'm screening at the same time and so here is a paper from lab chip where we actually use solid biomass to basically use the Doppler to do her genius. Which are very hard to do in a micro plate because it's very hard to dispense solid biomass most of you are chemical in the newest you can you can easily figure it out that is very hard to dispense solid biomass we figured out how to do it in droplets and you know problems however. There is a letter from that. Droplet microfluidics which is something called Digital microfluidics where we use electro wrapping. I don't know exactly what the mechanism is but by activating these electrodes you can really concur the hydrophobic city of your surface and hence also you're changing the contact angle real time and make the droplets northbound and you can see you can you can type it so you can see this one is being prepared to start with the big droplets you can just a small property equivalent of by padding from it as it arrives and then you can miss them and you can see that movie being generated there is actually a company called logic came out of Duke University. The big sequencing company recently so they're doing a lot of this work so don't think that we have the first one to do this you know we're just using it for different application and the advantage of D.M.F. is that you have absolute control over things like mixing making the droplet sartin. The disadvantage is throughput because you can only do. As many unit operations the number of electrodes like are fewer than that and. I think if you want to do ten thousand reactions you have to have a minimum of ten thousand electrodes that you have very expensive. Going to college that's not expensive but here for microfluidics that's very expensive and we don't really know how to scale that up. That ladder for droplets in China rise to speed and so our concepts can be combined the two so take the high throughput advantage from droplets inflow and let them keep them flowing and we don't need to do anything fancy to them such as give me a sense things like that because they don't need to sit on an electrode to culture but when you want to mix the two things like you know added about it to your culture media and then we bring them to an electrode and we do that sequentially so I want to you know one drop at a time and then put them back in the channel again to incubate for however long long the need to include it and has read quite well is still a long way to go. And these are the kind of unit operations are molecular biology operations we wanted to do will be just where everyone from the beginning start with the D.N.A. part so you have that example I showed you spotted of six. And ten Brussels of each gene you still limited sixty so having sixty inputs to a microchip is not that complicated if the Communist come in a totally space that gets very large because it becomes ten to the six and so we wanted to do and was mixing of the other parts together with the plaza made on the chip. And then do some culture because at the end of the day that's what you get out of the chip is the cultured cells then obviously it has to be a scaled up we want to test. The number of different conditions we want to make sure that it works with many different techniques that are commonly used by people doing metabolic and. Biology such as Golden Gate Gibson you know don't ask me why those names are you know they just happen to be. People who use them because one better than other depending on the application but rather to see that all of them can work. Under Dick this entire box and put it in a chip or multiple chips for now so here's an example just published in the synthetic biology where you can see you can also see the channels so it's kind of the combination of the two formats of microfluidics And so we do all the D.M.'s only because that's all mixing that's all merging of droplets we do them all on electrodes but when that had been done we let them do in this kind of challenge and that's where they have the. Operation going on and you can make a second dying to just add the residence time without making the chip bigger. And then we have another set of electrodes to bring in the cells so we can do the electrical transformation and then we have an outlet which we also have some built in volves to make sure that there's not going out when we are not ready to but we can also extract cells out of this chip and do a kind of regular culture and this just shows you. That we can actually achieve all those kind of medical molecular biology steps it actually works pretty well we have shown it found all these different methods to get that has happened at room temperature Gibson fifty to get a better as we have a peltier heater at the bottom of the chip because obviously if you want to do it at fifty degrees you need to have some kind of heating element but you can just take literally bringing a peltier unit to the backside of the chip and that's good enough and then we did some modeling just to make sure that the heating was done right. And we also did used we did. And we also did. I think fungus the pipe and again through these quickly you can see how different a step. You know I read I did just to make the movies. And kind of that I got them shows you that all you have to do is have a good control software for very dangerous for the electrodes and so this part better get complicated Right I mean if you have that many electrodes you have to now run lines to. Get them out of the chip to connect to a pain or something outside so that part that's got complicated and kind of has a limitation and scale up in a sharpie we just did kind of sixteen. Droplets and sixteen different combinations very good sequencing match for the I guess on reason. And in the last part of the chip rather transformation not really we can do a little present to the last chip we did and I like to present I think I skipped it too quickly so that we kind of format a bit of the curves fairly close to each other so we can generate high enough field to electroplate the cells we can also do. Because that's very standard we wanted to make sure that can we develop a form of a chip where we can do huge shock and here is a kind of chip on the right you can see the different temperature regions forty to thirty seven zero degrees so you can kind of a stirred things up to whatever the right compressor is for each of those just steps are gay rights right where. We can do you know multiple different type of protein again. Not to be but there nicely for us and you can use that as an example the same chip can do all three we did hundred Doppler and they look almost identical so that means there is not much variation from Doppler to droplet. And we also did equal I used a fungus and you know it was compatible with all three and I'm certain I'm not that that impossible is just you have to test your chip with many different things that the biologist would like to do to make sure that it actually works not just with one type of cell which is. Because whether someone is interested in East or Niger and yet they were actually quite well in this keeping a lot of details we had to do a lot of stuff as chemistry and. Anyone who does droplet knows all these kind of pain points and so we didn't spend a lot of time optimizing a lot of those conditions before we got to that. So where are we going next I want to kind of leave enough time for questions. If you. Don't even have to notice they're all kind of different we did one for here chalk one sort of you know. To actually finally integrate everything on one chip all you do is have these sixteen lots of sixty. You introduce Not sixty three million sixty because you have to have like rushing before and things of that nature. But then everything else gets done a device that looks something like this and has tons of Rives obviously coming in and some outlets for the liquid and. Probably liquids out you can also notice that this is another thing we pay a lot more attention at a national lab is that this is fairly well engineered in terms of we're not using. Stock in a pretty as Chip as our use kind of realistic involved in things like that so that it can be eventually be sent to other places places other than J.B. or if a company is interested you know they have actually a decent a starting point in terms of engineering itself. And I would usually just kind of again we need to be a little bit more applied than he was that is so we tried to bring it closer to where a company will pick it up and that the first challenge. You know and Pam is working on this to you know we need some really good idea there to actually to be a challenge as well that is listed here philippic acid How do you know that your cells are making what you need them to make because most of them are not going to be for us and it's easy for me to show you P. and B. if B. and B. and all that by. No one cares about those things. So if you're making butanol especially on this a scale it's almost impossible to detect. Droplets from Nice ideas about can you have a proxy for that compound being made. Investigating connecting the Doppler chip to him I suspect very sophisticated ma suspect platform developed by a colleague of mine a lot of Berkeley. But I think there is room. For improvement and second part of the biggest challenge is establishing a scaling laws just because you can do the communism here and it works really well how do you know that that would be true want to scale it up because eventually whatever it is that I'm making in my chip needs to be a scaled up. If not more to make something real and if it's bought by a fuel that will be you know we're not thousands and thousands of gallons. So how do we know that just because it works on the chip will work or just because it fails in the chip it doesn't work at higher scale and that's another thing our grill actually is not to do it in the chip we do it in the chip than we do it in the micro tighter plate than we do it in millimeter scale then need to scale flask to also started stablish ing scaling large as we are kind of shrinking down the assets to see you know what those labs are that govern. Taking things from this a scale to have hundreds of liters of scale. Stop their. Tank most of these people anyway but obviously it took a lot of money from many different sponsors to make it happen and I listed some of the grounds that contributed to this to thank you all and I'm happy to take questions. I. Yes. Very good point but was that two slightly different aspects what I meant by this is that as you do that everything works perfectly in your droplet microfluidics. How do you learn. That once you take it out of the droplet and your knowledge of culture between the same right and that this is one of the big microfluidics is that if you want to scale it up you have to establish that things work that's I mean you know I showed you in a meeting last year and I'm going to be doing the chip we compare it to rock the greatest and that is now so you have a similar level of effort and bring in some good model. Because if it if everything works like a charm and everything I do and operate it works just fine at hundred leaders scale that is nothing to be solved but we all know the answer that it would not be the case right so then you need to figure out what is the problem arises not a scaling up because it's not you know the molecular biology should happen the same way but we learned that in a culture in a. Test tube is different than the culture in the micro Dr Well we should different in a culture in a hundred or floss and can actually i'm lot of that it has to do with chemical engineering right I mean it's the lots of other things that come in and that's what that's what I meant by a scaling laws rather that that I'm not reproducing rather left in my chip so that my results are very different than what you will get at a bigger scale the second baby that's a very liberal because yes you know. And that's also not solve the yet I mean there are a number of companies that are trying to do that but it's all very early stages and they're all focusing on the market. Reactions and be the one millionth reaction identical to. The first reaction I had and that's a very good question because by the time even if each run even if you do have a frequency of can hurt there is a huge time gap between the well the first droplet and the millions how do you control for that right I mean you know how do you detect all the so that you have so that's a lot better scaling problem but very far from this we just want to show the proof of principle around two thousand I think companies that I want to come in and then take that second part of your question. Yeah. Yeah yeah. That's pretty easy because typically you are going to do what you can do you have to interface with something that will take you Michael leader so in the studio I showed you can type in directly into that that's not a problem when the center think you have a very good point so just to give you an example of how companies are doing it now. If you look at. Device that is being sold by Illumina but there have been a typically they have a micro tighter plate on top of their chip. So it looks like just like I got up late and you go directly so they have this plastic manufactured that is cheap enough that they can put it right on top of the chip and inject right there because that's much much simpler than coming up with an interface to have something like a micro hydroplane it can connect directly to the chip that's much harder because of the. The volume in compatibility you typically by putting in. Your electrodes when you need sub micro leader how do you do that very accurately so that's still a problem some kind of answering it in a long way that's where one of my kind of biggest issue with how this field works that's when we need to develop some standards. On the community we need to figure it out and run it will be how do we interface with micro tighter plates they're not going away they're used they're very useful and there's a lot of money invested in it and it's going to stay there so I would say for the synthetic biology chip dancer will be a make I need to make my device compatible with a micro. Because everyone knows that everyone can give you D.N.A. pieces on a micro plate and then and both input and output right because if I gave Pam an output which had my provider played with cells she knows exactly what to do with that next and so I think we need some extra. You know the other option would be I make the inlet and outlet customized on the chip and that will work but then you have to have enough market that you can you know because that adds cost so then you have to have can you really. Have that cost in the price of the disposable for sequencing it's OK you can do that but for a lot of other applications I'm not so sure so they're not really depends on the application but I think you know in some way to be nice if everyone just agreed that their chip will work with A three eighty four plate. Because you know that's a standard and everyone has it and I think that's something we have not solved as a community. OK. So. The mission but it will be and probably professors would not like it ask hard questions as to why you are working on the project if it's a rock solid thing. And you know I will tell you my Ph D. I mean I just rot in my professors and this is about doing the work on and I was just so happy that I had a project which was founded I didn't ask any single question I did because there was another that everybody outside my advisor. Who is happy to jump on that project and so maybe you don't after. Getting assigned get assigned and then professor knows that you know that I stuck with you and then you asked that question right but it's a very little and I mean everything is available if your child walks out of it going to go right I think that's something I learned very late in my career. Second when it would be. You know just kind of a scale of things how I live the very best expert in using this device in my lab. Well once you leave can anyone else use it in the same lab or somewhere else and to put you know put some attention to that as to. How practical it is and if it's taking you three days just to get the chip up and running after the tenth I mean of course in the beginning it takes three months to get the ship up and running but after you have the power lines you know from the perspective of who the end user will be so that two of them are very connected. And kind of goes back to you in that particular question right so we think about that very seriously now and one thing I've realized there is no good going to solve the problem for me but I think that would be pretty pretty useful to be used modeling I mean that's all the third thing I would say modeling saves you a lot of time if you can use it and there's some really nice packages that are already out there which have been very very user useful for modeling and simulation especially if you're doing kind of micro for that kind of thing they're going to teach you a lot more than you think and it's a very go to scale that it fairly widely needed like national labs and companies. Most of the national labs have. Licenses for the spend most of the micro for the packages because you can afford it at the lab of thirteen thousand people and so if you want to come use it it's almost free for you and really look for that skill set because it's impossible to hire a model or just for your project. And if you're good at modeling then and stimulus and you also have a better to medical understanding of what's really going on. Thank you.
