Particle switching triggered by a focused laser pulse. (a) The main channel is 80 μm wide and is split into two 40 μm wide channels after the switching junction, one for collection and one for waste. The bubble excitation channel is 200 μm in width and increases to 450 μm at the bubble excitation location. The nozzle connecting bubble channel and the main channel is 50 μm in length and 20 μm in width; (b and c) Time-resolved images showing a jet created by a bubble. The bubble expands to its maximum diameter of 160 μm (major axis) in 5 μsec and fully disappears by 20 μsec following the laser pulse; (c) fluorescent trace of a non-switched particle and (d) of a switched particle.
