Soft Lithography Methods of Fabrication

2020-04-29 , Joseph, Paul J.

Soft lithography (SL) refers to a family of techniques for fabricating or replicating structures using elastomeric stamps, molds, and conformable photomasks. Fabrication of microfluidic devices by SL is the most popular approach due to simplicity and low cost. In this approach PDMS (polydimethylsiloxane) is cast on a SU-8 master mold to generate elastomeric stamps that are then sealed against glass slides using oxygen plasma. SL plays a vital role in microfluidics, ranging from simple channel fabrication with inlet/outlet to the creation of micropatterns onto a substrate surface. SL includes a collection of fabrication methods that are all based on using an elastomeric (or PDMS) stamp. These methods with reference to Microfluidics device fabrication (µDF), Replica Molding (REM), Micro-contact printing (µCP), Micro-transfer molding (µTM), and Micro-molding in capillaries (MIMIC) will be presented. The goal for this presentation is to impart a basic understanding of soft lithography for microfluidic applications as practiced in academia and industry.

Southeastern Nanotechnology Infrastructure Corridor (SENIC) - A Regional Research Resource

2020-04-22 , Joseph, Paul J.

The Southeastern Nanotechnology Infrastructure Corridor (SENIC) is one of 16 members of the National Nanotechnology Coordinated Infrastructure (NNCI), a network of academic user facilities serving the needs of nanoscale science, engineering, and technology by providing state-of-the-art equipment, staff expertise, and training resources. SENIC assists researchers with a broad range of micro and nanofabrication and characterization projects, such as nanostructures, nanoelectronics, MEMS, biological/chemical sensors and systems, biomaterials, photonics, materials growth and synthesis. This 30-minute webinar will provide an overview of NNCI and SENIC with a discussion of shared lab resources, external user services, and education/training programs followed by Q & A.
