Abstract: A device for separating fluids includes a microfluidic channel with one or more wall filters or membranes through which portions of the flow in the microfluidic channel can be removed. The wall filters can have precisely defined pores therein which restrict the removal of certain particles while allowing other particles and/or fluids to freely flow therethrough. Because of the high and uniform pore density and low flow resistance of these filters, the pressure drop along the microfluidic channel may result in a negative trans-filter pressure, thereby causing reverse flow of extracted fluid back through the filter and into the microfluidic channel. Precise design of the microfluidic channel and control of flow characteristics can minimize and/or eliminate this reverse flow while allowing for sufficient sweeping of the filter surface to inhibit clogging with particles.
