Abstract
A microparticle sorting microchip for a flow cytometer is provided to enable sorting of microparticles at higher speed, higher purity, and higher acquisition rate. The microparticle sorting microchip includes a main channel through which a microparticle-containing fluid flows, a trap channel coaxially communicating with the main channel, a trap chamber communicating with the trap channel, and a gate channel intersecting the trap channel. The trap channel has an opening intersecting the gate channel. The trap channel has a smaller cross-sectional area upstream of the opening than downstream of the opening along a direction in which the microparticle-containing fluid flows.
