flow cytometry fluorescence-activated cell sorting fluorescence activated cell sorting CHMO:0001085 A method for separating microscopic particles suspended in a stream of fluid. The particles are forced individually through a vibrating nozzle, then exposed to a laser beam and the resulting fluorescence and scattered light is detected. Finally the cells are sorted by applying an electrical charge to droplets of the fluid and deflecting it to the left or right using charged electrodes. FACS
