Unformatted text preview: make conventional flow control strategies useless, 2) If surface area or volume is large, then the surface tension interactions with the wall become important and, 3) Most methods of fabrication are planar and moving parts tend to stick and jam. With these challenges, microfluidicists have developed methods of controlling flow with tripolymer blocks and other valves which help to control the rate as well as flow to obtain either a efficient mixing or flow within the system....
