Microfluidic system for particle manipulation based on swirl

This paper proposes a microfluidic system for particle manipulation, which is comprised of chip, driving device, manipulation dish, and associated accessories. The chip integrates swirl structure with three microchannels, allowing trapping, rotating, transporting, pairing, enriching particles different parameters by controlling the jet velocity each microchannel. device mainly constructed push–pull syringe pumps to ensure stability flow field during manipulation. Experimental results demonstrate that developed can achieve multifunctional long-term (hours)
