Types of Lithography Photolithography ◦ Computer Chips ◦ 3-D nano and micro materials Soft Lithography ◦ Lab on a Chip SHINE: Seattle’s Hub for Industry-driven Nanotechnology Education 2
Negative Photoresist Unexposed areas are dissolved away SHINE: Seattle’s Hub for Industry-driven Nanotechnology Education 3
Soft Lithography Begin with Photolithography to create a mold Fill with a polymer Lab on a Chip Repeat with the mold Silicon wafer Microfluidic Device SHINE: Seattle’s Hub for Industry-driven Nanotechnology Education 4
Microfluidics Control and manipulation of fluids Deal with Small amounts of fluid Small size SHINE: Seattle’s Hub for Industry-driven Nanotechnology Education 5
Lab on a Chip Applications Immediate detection of bacteria, viruses, and cancers DNA extraction Biochemical analysis Environmental analysis Used by NASA to analyze surfaces of the spacecraft for bacteria SHINE: Seattle’s Hub for Industry-driven Nanotechnology Education 6
Lab on a Chip Benefits Portable Instant Only needs a small sample Cost effective Eliminates large laboratory equipment Manufacturing is less expensive SHINE: Seattle’s Hub for Industry-driven Nanotechnology Education 7
Parallel Analysis Can run multiple test is little space Direct comparison with a control and a number of samples SHINE: Seattle’s Hub for Industry-driven Nanotechnology Education 8
Laminar Flow Fluids that flow smoothly and with no disruption will flow in parallel Turbulent Flow Fluids that flow coarsely will mix Demonstrates one way that fluids can be controlled through Lab on a Chip and microfluidics SHINE: Seattle’s Hub for Industry-driven Nanotechnology Education 9
