Microparticle sorting apparatus, microchip for sorting microparticles and microparticle sorting method

摘要

There is provided a microparticle sorting apparatus including a main channel through which a fluid including microparticles flows, a branch channel that is in communication with the main channel, an actuator that causes a negative pressure to be generated in the branch channel, and a drive unit that controls a voltage applied to the actuator to cause a change in pressure containing a step waveform component and an undershoot waveform component in the branch channel.
