Abstract :
We report a high speed and high purity pulsed laser triggered fluorescence activated cell sorter (PLACS) with a sorting throughput up to 20,000 mammalian cells/s with 37% sorting purity, 90% cell viability in enrichment mode, and >;90% purity in high purity mode at 1,500 cells/s or 3,000 beads/s. Fast switching (30 μs) and a small perturbation volume (~90 pL) is realized by a unique sorting mechanism in which explosive vapor bubbles are generated using focused laser pulses in a single layer microfluidic PDMS channel.
