The following podcast takes on the form of an episode of a talk show called Science Today.  In the episode, two specialists in the field of nanotechnology are interviewed about methods of microfluidics and MEMS development.  Microfluidics deals with the behavior, control, and manipulation of fluids on a nanometer scale.  The importance of these technologies lies in the evolution of healthcare, specifically with the development of point-of-care diagnostics.  MEMS stand for microelectromechanical systems; they are small devices that integrate mechanical and electrical components.  Photolithography is one fabrication method of a MEMS device, as you can see illustrated in the graphic above.
