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.
