You know I'm right here. Research cancer research might be faster or their research really touches on understanding how cells where we are about these things. Thank you for the current introduction. Can you hear me in the back. OK so my name is Tony came the topic. I have today is engineering by marriage my persistence for another medicine for another Madison is for us still leaving the translation. Now on the medicines. As we all know the medicine is just defined there is it medical to occasional technology many people who are trying to create really so few skated the particles which has a certain encapsulated. And targeting organs and imaging Egypt and now they campaign multiple imaging agents and drugs within the novel particles were inside core. So we call this motif. We've noticed targeting I go What happen is once we inject or ask the patient to have this throws then you will spit out the body as expected and we will have a certain style. Effect which is not really important in most cases but when you think about the cancer. If you want to really kill the cancer cells in your body you don't want to get this side staring you in through the belly. So we want to make this target a certain area which all the cancer cells are tumor cells around. So the target is important as Cup Rob strategist for example we can use without targeting Lyons just suspend on our policy in Europe world stream and using this premier ability because usually when you cancel cells located your blood bells will really really key and dysfunctional. So we can utilize to situations and just spend another part of trying to keep those nano particles in your bloodstream. As long as possible so we can we can transport those drugs to target cells which is cancerous cells in this case and sometimes if we your cells really inflammation such as color of a school of these years and if you have a surgeon or her Couric clout. Then you may want to treat the best course of Anderson cells themselves rather than target cells. So you can treat. And make the situation better on the area. And in the last case you can typically target the cells inside. So in this example shows that we need to target. And we need is multiple imaging Asian intros to more neuter the Nano particle we suspend in your body. So we can think about the tongue Ryan of the critical stage on the medicines. Let me show you some representative. Not a poly cause people develop libels them since nine hundred sixty is pretty long time ago day used forceful it is standard nano particles which is clearly because you have hydrophilic surface which is stable in your burst. Three mm. But you have a certain look or area between there is a little smaller space for hydrophobia throws. That's why people are trying to going to make poor based on the particles which is better in terms of the hydrophobic throw building. But this lighter germ is still available. It's very unique you won't see you get anti-bias falling properties such as pagal ations to once you get this pad outside or weird right with them so you can you can make is not a particle longer save in your bloodstream and you can also put the target in wires so Doc still is the first at the approved nano particles in our timeline and you can also put a protein based or a certain in or going on a crystal or an outside and you can also make this a little hybrid hybrid type platform the polymer either four split by a layer or my cell in the poem or invalid my stills and now days not only just prior to this thing go. This after a certain type of teen star your body. You're using multiple targeting wagons. And now an apologist is going to very complicated. Then what are the challenges the challenges many people listen to leave poor in relief. How impact Jones like Chancellor Merkel Madison's so many papers. But still few drugs and a lot of critics because when you look at this graph listener Charles per year last year we had up to thirty thousand papers just depending on the nano particles and nano Madison with a certain drug and imaging agents how we can I be. To how many labs and people are working on this and around two hundred is applied and so made it for pate. And just hand is going critical triers just trying to make sure this tan is not in two thousand and thirteen is until now some of those rejected fail. Still we have ten critical triers some point to last year and every year from now the medicine. Maybe a few hopefully we can cope. But or none in years. So what are the challenges these peoples pointed out is to one is it's really hard to reproduce. Once we synthesize certain type of nano particles because like I said another public platform is getting complicated because we need multiple amusing Asian multiple multiple drug compounds. So even though I said the same companies ition. I preparing on the bench in same place same time tomorrow you will get a different properties. That's a frustrating and that's the one of the top challenges we have right now and it will be getting worse. Once you try to scale this up. Because why we need to scale it up because what we need is and you wait for own term we want to use this for a human body. How many how much drug we need for a human body compared to how much we need for just one simple the red or mouse experiment is totally different things. So the kids can really only get the high reproducible particles even skill and the other challenge is low success rate in animals to this uncritical try yours with her two hikers who you all know how expensive this to this are and once you develop and hope to marginal particles and make sure that disguise that good enough in India to study in your. Dish or any cells of your culture in the sheaf Berman. And then once you test it anymore. The small. You all. Most of the cast is the now apologise to fail and because that's the gap between our in between barman and even the small animal status. So let me show you the typical translation steps of normal medicine clinical development. So it takes you a couple of years to one see you have an idea OK this platform is will be geared for a trade a certain disease and you sense a slowing down of particles and then every day of the period and characterize them and feedback and go and go and once you make sure they're not the poly goes to work since the side and the optimal point you find then you can do some embitter evaluation and it will take some more years because you want to has that and get all of those small Arab or with different types or types and some point you can get some fail here and then you will do the same thing again and again this is who entire iteration process and then after that are you sure it has to be the small animal large animal once you make sure that this is working well it's not enough and this is the fix a C. of the targeting then it's time to secure this for a human body task and this entire Now days it takes a fifteen years. So one of my posts out Barger he said he created a platform nine hundred ninety eight and still is not the approved even though they believe that's really not a particle and not a matter since. So in my lab in my research interest is how we can make it IS challenges opportunities. So the kid we want to make highly reproducible in our part is one thing we can think about because the critical challenge is to be very sure once you make a lot of public today and tomorrow. Those about US has variations. So the kids how we can make this. Continuous process like you get a car or a certain product from the factory large scale. And we need to get the most people for uptick in than those agents in the non-apologetic trying to follow the current stream particle product and finally we also want to make this kill this so we can in in include dispensed opt in system of cats radiation process and scale love with this one process making multi-functional materials in large scale. And another thing we can do in a lab is how about we can make this evaluation process much more similar to what's happening in vivo. So we can we can make to the platform and the system physiological lovable and so for example mechanical actively environment and so we can control the properties of mechanical stiffness in years to serve the metrics pretty well homogeneously and then we can also make a special temple we control chemical factors not only Sure stress but also what's happening in the beta side of your cells and between yourselves and electrical signals. So this is the wrong term goal or what we are looking for looking to and we believe this two steps really helping contribute to reduce the duction the entire clinical development of this and on the medicines. It's sold on some go to today. What I'm going to tell you is two aspects in that pain in terms of manufacturing. So we can. I'm not going to show you real manufacturing none of my distance today but I'm show you a way the approaches using microchip a little larger scheme micro for the chance. And how we can get a better potential for the non-manufacturing and the other part I was show you how we can test those normal particles in a Magic. Mike when bargains simply mimicking the end of supreme ability how we can actually study the translocation of nano medicine in vitro so we can. Save our times and save our money. Before going for the mysteries. So let me go forward this to topic for the first. So this is motif company and look to phones and other matters. There are different shapes and geometries. We can you can also work on engineering the surface chemistry and there are different type of platform and you can combine some of this may get one from unique and take advantages from both platforms and you can incorporate this in certain not write ins. To get a certain cells and bodies to trade a certain. For the same vision and also. And as a protein a peptide so you can also induce a search engine expression change in your cells and when you bring a certain acid in like you are in a anti-microbial or a certain D.N.A.. What I have been doing is I'm I'm choosing a certain platform and trying to make this process better with my microchip So this is the hives I have been developing with my microchip with the same microchip the changing the optimal composition. So like I said the force of the field by the ears and pulling out apology with a surgeon anti-bias following prop. And you can you can get the both the bandages with this little point on the particles. And I'm going to show you the high density protein of the Constitution in my microchip today. So let me focus on this to perform today and how I make the system. Better to synthesize this now part. Some of my not really familiar with look at the particles look for another particle is like a hybrid now partly it's the advantages from two different platforms point in our politics and life assumes and pulling out of politics like you mentioned is good for cooperating hydrophobic drugs which is limited in life and reaches for the poor worse all drugs and usually most of the side of Terri cancer drugs is high the phobic so this is important and leaping the layer between the core and shell which might be unstable but when you think about this to hide a full week and this is either a full week. So this will make the system will promote the drug with tension and finally in has capsaicin efficiency and with the bandages you can get the serum stabile really so hydrophilic shells it with like I said you can make this stable a longer. Stream circulation. So this is two different times over. Particularly since the start of my study let me show you before going forward or I'm going to show how hard to get highly reproducible down Pollack. From the bench top conventional precipitation. So now the precipitation is one method you can make the leap and on the particles. So you can get the whole member and the full with drugs in all. Face and dropped is to the face of the lip it. Why we are using drugs why addition because once you add a certain amount more than a certain amount the polar is really easy to work again. So you cannot stop the we gaze in that you cannot control the side you cannot get homogeneous Now apart. So we should use this drug wide which means depending on the people practitioners how small we should use no one knows they have their own protocols. So that we'll create other vacation. So like I said this is for reproducibility it's to expiration not just the process and because this is look simple but there's another thing between the way for certain time and then in a live it over and strain to make the system stable solution stable between organs just is and how to control the mixing process because drop is a strong we can control that's off side with this man you're preparing and it's hard to incorporate multiple complements and if we want to issue the ink and insert as more steps. So usually takes likes a day or a couple of days and most the first reading port is interplay of the properties. I have all other qualities and MIT this is a sign of a particularly people now are probably still there doing this because this is one of the best approach you can make a high quality people know Pollock holes but the question is even I am doing the same problem just today and one of my colleagues doing the same composition and there is still very ancient but the problem is even I change the composition from one end to the prophetess is not independence. So if you change a certain. Because. Particles. If you change the Lippitt concentration and pull them a concentration a certain type of the target and proteins all this content ration and composition will make this one our particles and those compositions into play each other one another. So once you change one you should think about how this guy effect the other composition change. So that's a frustrating process too as it's very hard to find out which are fairly different type of properties many people use Mike to further if to since the side pulling on particles. So I'm not sure how many people are used to the micro for this but once you control the range of the number pretty low range then you can get this simple straight for streamlined without mixing but the fusion still works you keep the rain at the number of less than one rest and. Sometimes differently depending on the German. Cases in microfiche al. So you want to control the flow rate you can control the with and the feel the pad pull the particles can be says a size across this interface so you can make it a little faster and smaller and control the with and depending on the narrow part of the properties to your God You can get and optimize is just the problem if you can. That is still some longer than a couple of hours. Why is that because like I said pull him or is is it's a brigade. Once they are in a steady flow condition. That's why we stirred the solution when we make the people in our power tools. So why is there because even though you make a flow usually pressure the of. Microfiche L. has closed the profile. So you're in year the war or real brigades over time and finally clothes challenge. And some people working on the same process. This is a diffusion basis is this what about how we use our come back so they use come back. Ssion a certain type of mixture inside there are a lot of different type of conversation I mean Michael Food Channel. So they can develop faster and also a little poem around Apostles which cannot be fixed by diffusion but still the same problem the poll him against because they the now. So what they develop in the same lab is OK we can make this really focusing and so we can keep the podium or from the center stream on the center. So we don't have to worry about to put a motivation and it worked out so they use this device to synthesize probably cols But still to me. They're using the fusion. So once they mix using a certain chaotic mixture. We cannot guarantee the poem or a gate or not. So this is still limited to go through which is our the reason I'm taking the number here is our means we need a certain a few grand for one mouse studies for did is we need to make this like several days several weeks just for a couple masters. This is the month we are making use of microfiche I know once you use the fusion. But there are many people working on this fully the mechanics that flow parents know how about we can change the geometry. And using a certain convective mixing or sometimes in a show of force in microfluidics So this is the I call the secondary flow formation. So once you make a search in the group because I was. Bottom of your microfiche. And you can get the circulation flow on this from the certain faction and they will help you separate the micro particles. And sometimes they can sort. The particles depending on the flood because we call this the in for. OK mate is secondary flow to simply make the channel curved like this and they can optimize the length of the channels so they can get is like a Pollack who separated. Which is impossible for a nano particles which is one thousands from over. And this varies with changing the just size actions and make the stream focused on the center. Which means that we can use this was we can mix the nano particles to the political solutions because we can to avoid the problem of creation and there are some more high suppressed or they say. Using some of the homes and trying to analyze the particles in the center. So one thing I found is many people using simple three in that channel and you can see with us a certain range number. Which is a little small fifteen then you can see this in your interface between these two was the use of blue dots just three in the red on the sensor what happens if your stream is pretty straight forward. Until you clear the height of one hundred while before you increase the high three hundred and trying to maintaining trying to maintain the arena's No fifteen we can find even that small they know the number the microphone Pad and the whole forwarder. So we can see this kind of pattern. One of the reason is because is this how to stream. Can create a certain separation wants to increase the. Height of the channel and those flow pattern is three dimensionally sensitive. So not many people using this power because it's hard to insert a new inserted to be in the micro scale. But what if we change this. If we change it is simply just directional The you can change it totally up in the downstream which is focused which is very useful in many occasions I've only seen societal walls to match very well happen is you will get the separation and the intersection and that separation can create a search of the circulation and a type of microbe Otis's So this is the what's going on in the section and there's a micro vertices in the corner in the here and there was a change in the edge of the trees. So I thought what if we use this mark of vertex to be steered to because solutions and still maintaining the focus impaired on the downstream. So this is a simulation stranger simulation so I can control. If I keep following this number ten. You can see it is the Fusion and the in year two for particle living here parents but one seeing Chris ring there's a number from ten to two hundred you can see this different. Pattern transitions a certain point you can get mixing pretty well mixed situation between these two streams and you can still get the focus impediment. So I use this device. Which has a four hundred my community hall. And all to monetize the micro boards experiment to synthesize the people in our part and the Chivas through simple three unless parallel. And you can see is up to one hundred one thousand. Runs faster in terms of process rate is a cramp or hours so you can make another particle in a continuous process. For an hour for one mouse thirty which is totally different situation. Environment when you have him be able to this. And yes we can we can avoid the problem of creation with the by one or more of the bears we can take from these devices you do what we need to do once do you want to change the size of particles. You should change the composition Lippitt and the poem or some depending on the your platform but this devise. You can change the side dynamically once you change the way numbers. If you keep the repeated poem a competition at hand. Just change the rain is the number you can change the size of who it is big deal because size dependent. Since this is takes days and weeks and months. If you want to get optimize competition. We have still some property quality issues. Depending on the Brainard's number but you can still figure out why this is not near because of circulation patterns in Offaly developed so once a week hip a certain range of rain has a number we can control the size of not a particle dynamically without change the composition of little importance. We also tasked is how much how many multiple drugs and imaging energy that we can also. Combine in this same microchip. So dogs stary for you can kill the cancer cells with this. And as our rafts and try and Janick. You can carry your understand cells come down so close crystals is a good. You know for extra microscope and city detection and you can. The Using pegylated and Tyree by founding properties and sysadmin for near infrared. Fluorescent imaging. So we have your model will be able to pull up to compounds. So we can see or read the rate is hydrophobic. Characteristic in the core. And this little bit and this in across the shelves of the people in our part. We are using a third sense of the ship because solutions and using the optimizer microfluidic patterns so you can get is the people not a particle you can see all the calls captured inside with very dispersed the opposing one. And we can target a certain size eighty five or seventy or sixty five. Based on this device. So we pass the performance of the particle we developed so you can see the drug will this which is depending on where to look at it in your now particles. If the drug is in the shell you can get a faster through this. If the drug is a coup or you can get will slowly drove this. So we found the point that is true is in the same which is on the day twenty four hours and we tasked with with that show you. For that time period. We have one of the best kind of cells and the cancer cells and tested to prefer of these drugs and you can see the Depending on which drugs. We use in control and just down the particles and those ones and ones are multiple draws you can see that to perform a combined effect and you can also see the C.T. mages by see theme it is all non crystals and images for size seven. We also value that is the approach we inject if we use of a injection of. So you can see the accumulation of apology. In the mouse. Let me move on to another of another popular toy we created before going forward we all know what the high density lipoprotein is it's good cholesterol because they transport. This we saw cola lever's cholesterol transport. So it's there will help you to remove a certain Lipitor accumulation in your blood vessel or on the cat heart area so it can help you. Make your healthier in terms of your vascular disease. So this isn't that sort of you have your eighty and your body and this which means it's very stable by a comparable biodegradable in the genus and also long stories alive have a search and quest for and so I lifted a ship in the rules to distill it can be the constitutive but just by Batiste process. Let me show you how Usually we make the heights. So we have lifted an affable and crystals because we want to track where the allocated. So we are using an imaging agent and depending on the cat's rest of imaging agents we can use a certain already servants. So you can get the mice still and there you were you can get this this time because today to do a case you can just add this leap into water induced a step assembly of my SIL's and you can and. And April like a protein a want to get it and in this case you can do or more times it's a bit Crystal. So you can get another my cells and and of course for encapsulated in my SO and then you can the protein again. It is cooperative they consider. It has like twenty four hours of video Boreas you should stick to it all the process. So we did the same thing we reconstitute H.E.D.O. the same microchip the changing the optimal competition the flow rate and you can see different materials we can make. So we can make just simple disk. This is called the edge of the L. we call the microwave studio and you can also incorporate the four big molecules and step in which is why the four drugs. We can incorporate call their own and contemned out for their emissions. So we have to ask how fast we can make compared to the conventional benchtop process. We almost up to eighty times faster and you can see them of course is very similar. All right Sibila present the cost is actually the early constitutive by the bench the process and in terms of you know the steel we are a child who are you know we have a problem to make you feel better but Michel for the cello. This is the same because they see their process and we tested this age in macrophages so you can see the cluster afterwards microfiche is. With this our microphone and the human plasma. We call in nature and the conservation of issue of the similar cholesterol afterwards. So we think this is. Michael. For the benefit of years prior to two. And we can also like I said we can incorporate hydrophobic mole tools. So we can detect this H.E.D.O. when the cell takes in vitro and we can also. Incorporeal hydrophobic through standing. So you can task pro in private to factors. How was to you to see from Asia of the Mecca fish which is pretty activated and Everyone's to we add the stereo very well you can see the reduction of the seclusion from the metaphysics and you can also see that all incorporated in hindsight incorporated the else. So we can use this in C.T. erector microscope. And M.R.I. to summarize in this part we successfully produce the now part of a large scale with the potential manifest manufacturability of this material. So we use a single still assembly which is important in single layer a single to platform the still we have potential to tell lie generation. So our personalized gram per hour can be killed on power was a business that was to make this largest scale integration system. And with a certain precision control of this multi poor single chips and we can also incorporate multiple throws imaging agents. So we can create much a company out of the three platforms. So let me move on then once you make the nano particles and how we can test this better. Compared to the M.B. traditions. This is in general might by a man Microsystems like trying to maybe a certain structure and functional reading systems are what we need is we need a certain three the architecture because we need to think about what's going on over the cells what's going on beneath the cells and we my want. Coacher different types of cells and up and down near by. Three The synthetic scaffold is very important and we need to control the mechanical cues like for example shoes dress and the stiffness of your mattress. And then we should control the chemical factors and not only the nutrient a certain type was to lie. And we should also keep the electrical potential which is usually open look before entire system issues to control the article as well. And all of this control sure the be spatially and tamper with a delay of the many people trying to make a certain we call so-called organs on the chips or even the human or chair. This is two thousand and ten and science they use a simple layer market share with the host membrane and they use a vacuum pump so they can stretch and contract a membrane which will give the end still cells stretches and constructed over time which can mimic a certain function of what's happening inside your loan. And this is a letter to stimulation. So you can create a certain feel. Which is muscular thin film so you can connect to cigarettes. There you can stimulate that and you cane use the contractility and you can steer the work environment well kind of situation you can get that kind of contractility A muscles and you can also develop certain basic Larcher. And wrapped wire colors in one and you cane views the street the sprouting which is very important in terms. Earth. So they can study and try and Janick. Phenomena with this microchip. And now these people are also working on the integration of all these are going. Whether they're focusing on one organs and their function and structure. They're interested in integration. How many oxygen. How how high concentration all season and pressure and carbon aside a needed how we can control this pretty well in a search and this entire systems. What I'm going to show you today is one simple the idea of microchip moral they can mimic a permeable and the ferry which is very simple very important if you want to control the liability. So let me show you why this motivation was me what the beige and come from this is a terrible process. If you have process. There's a nail vassals can penetrate being there a certain type of the bait. When you treat other courses. Can you just leave or your nano particles in this large other is this blood vessel or this now Paula cools can be the reverse to the nail vessel in the other side. So what we think is out there might be both ways for many people believe that it will not happen through the naval vessel. So we tested with this hypothesis that the particular cumulation is full force of the twenty that by highly permeable now baffles penetrate into the plug from the network. Michael Bessel the supplier the world's largest. So the aim of this is develop a simple in-vitro measurement of underserved. Well maybe once the you stimulate in the Syrian pour in forever from A to tractors and control the show stress patterns so we simply develop a poorer and lower layer and inserted a Michael poor membrane. And an incorporated lecture. That idea we got from even one if a commercially available device and then we got is devised with the Michael Jackson embedded so you can culture cells and trying to get the video depending on the. Year in the frame over time. So if I.T.C. alchemy is common combination of mess of the brain you. Check the ability of your mono layer. So we got this correlation simply we changed the problem of media and we control the speed of said growth and you can see that goes up and the F.T. album in. Was We have higher population of industry. So we try to control the in the supreme ability. You can. Once you cut yourself with this in device you can get this part after two days and we can think about this model layer over in the stadium cupboard all the membrane of years. Microchip and then we can do we can turn a fall for and we can also see how the different was to be stimulated this pro-inflammatory factors and your body and the ceremony layer. Has higher probability so you can get more translocation means in both ways we can. Make sure the pony ability how things go. And once you take images. This is normal and the cells when they. Were established a model a year and once they stimulate certain information factors then you can get disrupted. Just serve. Interest or at junctions. So we says Assad using our device and nano particles which go in and five five foot fall because we want to make sure that the pope has a correlation. With the. With in my kitchen. So you can see it is limited so we have the people in our party. It's a durable deli and we succeeded in making the scale production up to some readers. So we can use this amount of Not A particular in various cities. OK. So what we did was we have mono layer of then the stadium. Then we change different tiles your stress disorder different level of sure stress from Point want to tan and then we added to their fault and for ninety minutes with this difference your stresses and they really move to they fall for a little bit another ninety minutes and see how they change and then we suspend our politics. And you can see this after three hours. How to you are very good and how what another part of the train is the occasional. One. So we monitor it. T R Every ten minutes and we. Sam pour the now particle from the low Traverse so we can compare. The nanoparticle translocation and T R And really pitted this experiment. We got some correlations that intuitively correct. We increase the ones we have similar to your Which means higher premiums really you can get more. And this is all the data point we go. You can see the jump when we change when we got the higher premier billion of these small a year and you can get the translocation higher not a particle translocation and when you look at this this is a four to five person and this is less than one percent. So this is a very high priest highly precise control of the system. Leather then what we usually do we fix the cellar up to the experiment and compare how we could. But how we can really say dynamically best selves and their situation hold forward and measurements. So in that perspective this is important. This to this important. And how we want to validate what we guard from Microchip in large animals. So this is the No more rabbit and this. Diet which can induce the article closes you can see the premier ability using this M.R.I.. And was excited and fired this error that you can see the difference depending on the site you can see the huge difference was we have the playing ability in this chorus and this is the more closer the images into yours that this is no more underseal self and keep the junction closed pretty. Well I was this is in this situation permeable you can see this permeable between this and the this is two microns bar. And we use the same batch of down the same day and doing the same Still the in-vitro in Beaver and we got to control part two cases using the five point five five and using size Fairbairn we can get their intensity separately. So we use all the mean for permeability test and we use another Politics various occasions. We did another part of the test cation using our people in our parts. So you can see the correlation between these two when the cells permeable the mirror we can get more particles and we got the same thing same data in reaching the same. And we got the same correlation with. And this is a curve closer images is the normal Basle and there's all fluorescents so you can see the vessel war and if we have you can see the nano particles accumulate in the plant and you can also see the micro features in the silly and the serious cells and this make a fish uptake of the particles more importantly we see that is now on the macrophages nearby in their vessels which is far from the Raj their phone other is so we can think about this now because. So it's OK to through the narrow vessel permeable. To summarize we've developed a simple microchip with live monitoring and to see your. Homie ability and we enable finally measurements. When the supreme ability and we believe this microchip is a unique tool for the nonpartizan occasion. So we can screen. Nonna medicine for other teachers too so we can control the pressure the French are. So we can control the pressure differential across the barrier because usually the cancer that is a high interest feature pressure difference. And also. We can we found in our politics as a case of for plot our giving a course at the site increase the probability and also the lunar cycle and obviously the real war and disintegration imaging. Show the similarity between the markets and the rabbit trail. So this is one project our lab is working in Georgia turned the previous test of this which I have done in MIT and is post. And now we are working on developing cheap little micro for the. Vessel one of the reason is if you have a right angle and rectangular cross-section like a for Channel. User and the seals of though I like the color and that means they will not really making establishing well established in the layer. So we are heading for this and still me trying to. Measuring the CIO are not only measuring the premier beauty but also trying to train their viability in the incubator. And also we are going to control issue of stress. So we can study how the novel pilots were created as well as interacting with this and this is. So we can monitor. The T.V. are trying them equally. We can change the chemical factors. So we can increase the probability of certain in from radiation. We are going to see particles developing new platforms microchip and try to optimize the flow patterns for different types of public to types. Thank you my mentors and family members and collaborate in Georgia Tech and the father who searches for the resources and the funding from MIT. Thank you for coming and take your questions if you have thank you. So just right. There are several ways you can characterize the rain there's a number locally. But in this is what we did is we just based on the entire volume flow rate through the downstream. That's the way we calculate to enter something where we are trying to find some localized effect that will need rain or to number all the other number how we can actually get some correlation between the certain flow types and the nano particles holding. Thank you.
