Abstract:
Microfabrication includes the techniques to construct micron-size features. The development of microfabrication technology has put many prospects into microfluidics technologies. Lab-on-a-chip (LOC), micro total analysis system (μTAS) or microfluidic device involves the manipulation of biological or chemical samples. Preparation processes such as filtration, pre-concentration, cell lysis, and derivatization as well as integrate reactions, separations, mixing, detections, and other lab functions can be conducted in a microfluidic chip (i.e. a microchannel). Microchannel is a channel with a hydraulic diameter less than 1 mm and Reynolds number is generally less than 1.
As a result, the inertial effects are negligible, the flow is laminar and particles (close to the neutral buoyancy such as biological cells) are expected to flow along streamlines unless an external force deflects them. The promising advantages of microfluidics have driven research on a variety of bio-on-a-chip applications in point-of-care diagnosis and clinical practices, drug discovery, biological agent detection as well as cell separation due to numerous reasons. This seminar provides an introduction to microfabrication techniques as well as microfluidics.
