DEVICE AND MICROCHIP FOR SORTING PARTICLES

WIPO Patent Application WO/2010/095391

A1

Disclosed is a sorting device capable of high-speed analysis and sorting with safety, high speed, and low cost by preventing cross-contamination between samples, contamination of samples, biohazard to the users, obviating the needs for an expensive flow cell and an expensive orifice part and for fine adjustment of the flow cell and the orifice. The device (A) for sorting particles is provided with a microchip (1) in which a flow channel (11) through which liquid containing particles is flown and an orifice (12) for discharging the liquid flowing through the flow channel (11) to a space outside the chip are provided, a vibratory element (2) for making and ejecting a droplet of the liquid at the orifice (12), a charging means for giving charge to the ejected droplet (D), an optical detecting means (3) for detecting an optical characteristic of the particles flowing through the flow channel (11), paired electrodes (4,4) arranged along the direction of movement of the ejected droplet (D) and opposed with the moving droplet (D) therebetween, and two or more vessels for collecting the droplet (D) passing between the paired electrodes (4, 4).
