This video tutorial is from Cornell University Mechanical Engineering 6240 – Physics of Micro- and Nanoscale Fluid Mechanics on Sep 5th 2012.  A discussion of two examples of laminar flow patterning approaches in microfluidic devices is included in this video: 

• Cell positioning in flow cytometry; 
• Pinched flow fractionation
