Manipulating Flow and Macromolecules in Microfludic  Devices 23:12 Questions:  (any 2 out of the three) 1) Describe some of the difficulties associated with controlling flow valveing and  mixing fluid in microfluidic devices 2)Draw the chemical structure of the triblock polymer used in the example shown.  Why do the two blcks segregate 3) Sketch a microfluidic device that would allow you to trap and stretch a large  molecule using flow.  Show the direction of the flow by means of arrows, and  show which direction a large molecule would strecch in this flow. Research She works with fluid flow with large molecules.  Works with synthetic polymers  and biological polymers ie: polyethylene and DNA respectively.) Flows used to process these material How to make these devices, you can make Parafilm on quartz (parafilm on a  glass side, though crude. You could also use PDMS: 2 part system gel at room temperature.  Better  defined features.
