Abstract
There is provided a microparticle sorting method including a procedure of collecting a microparticle in a fluid that flows through a main channel in a branch channel that is in communication with the main channel by generating a negative pressure in the branch channel. In the procedure, a flow of a fluid is formed that flows toward a side of the main channel from a side of the branch channel at a communication opening between the main channel and the branch channel.
Claims20
A microchip, comprising:
- a first fluid channel through which a first fluid flows, wherein the first fluid comprises of a plurality of microparticles;
- a branch channel in communication with the first fluid channel via a first communication opening;
- a switching portion communicated with an actuator to generate a pressure to deflect a selected microparticle of the plurality of microparticles into the branch channel;
- and
- a second fluid channel in communication with the branch channel via a second communication opening in the branch channel, wherein
- a second fluid flows from the second fluid channel to the second communication opening, and
- the second fluid channel is perpendicular to the branch channel.
