Abstract: In an example implementation, a method of microfluidic filtering includes activating a first fluid pump within a microfluidic channel to cause a forward flow of fluid through the microfluidic channel and through a filter of a filter loop. The filter loop intersects the microfluidic channel at a loop entry and at a loop exit. The method includes activating a second fluid pump to cause a reverse flow of fluid through the filter.

Abstract: A network of microfluidic channels may include at least three loops interconnected at a junction. Each of the loops may include a fluid channel having a length extending from the junction to a second end; and a fluid actuator along the fluid channel and located at a first distance from junction along the length of the fluid channel and at a second distance less than the first distance from the second end. Activation of the fluid actuator of selected ones of the at least three loops may selectively produce net fluid flow in different directions about the loops. In one implementation, a fluid channel having a fluid actuator may have a bridging portion that extends over another fluid channel.
