A fully integrated μFACS system coupling various sorting principles. (A) Structure of the μFACS device with microfluidic channels and a sorting PZT actuator. The cell trajectory plot under different voltage magnitudes to the PZT actuator was observed with superimposing photos taken by a high-speed CMOS camera. (B) Schematic of the overall μFACS system. The laser-induced fluorescence from the stained cells was collected by a microscope objective lens. Fluorescence signals were modulated into a time-domain signal of similar waveform via a spatial filters at the image plane and were registered by the photomultiplier tube (PMT). The output signal from the PMT was imported into the electronic control system for real-time processing. (Reproduced with permission from Ref [41]).
