Abstract
A MEMS-based cell sorter is disclosed, which uses a novel combination of features to accomplish the cell sorting using a microfabricated cell sorting valve housed in a disposable cartridge. The features include an interposer that provides fluid communication between the microfluidic passages in the silicon substrate and a plurality of fluid reservoirs in the cartridge, including a sample, sort and waste reservoir The disposable cartridge may include other features that assist in the handling of small volumes of fluids, such as a siphon region in the sort reservoir and funnel-shaped regions in the sample and waste reservoirs. A mixing mechanism may be provided for stirring the contents of the sample reservoir.
