Abstract

In one example in accordance with the present disclosure, a cell sorting device is described. The cell sorting device includes a microfluidic channel to serially transport individual cells from a volume of cells along a flow path. A sensor disposed in the microfluidic channel distinguishes between a cell to be analyzed and waste fluid. The cell sorting device includes at least two fluid transport devices disposed within the microfluidic channel. The at least two fluid transport devices include a cell ejector to, responsive to detection of a cell to be analyzed, eject the cell to be analyzed from the cell sorting device and a waste transport device to direct the waste fluid to a waste reservoir.
