Abstract

A technique for separating components of a microfluid, comprises a self-intersecting micro or nano-fluidic channel defining a cyclic path for circulating the fluid over a receiving surface of a fluid component separating member; and equipment for applying coordinated pressure to the channel at a plurality of pressure control areas along the cyclic path to circulate the fluid over the receiving surface, applying a pressure to encourage a desired transmission through the separating member, and a circulating pressure to remove surface obstructions on the separating member. The equipment preferably defines a peristaltic pump. Turbulent microfluidic flow appears to be produced.
