Abstract
A particle manipulation system uses a MEMS-based, microfabricated particle manipulation device which has a sample inlet channel, output channels, and a movable member formed on a substrate. The device may be used to separate a target particle from non-target material in a sample stream. In order to improve the sorter speed, accuracy or yield, the particle manipulation system may also include a microfluidic structure which focuses the target particles in a particular portion of the sample inlet channel. The particle manipulation device may have two separate sort output channels, wherein the sort channel used depends on the characteristics of the sort pulse delivered to the micromechanical particle manipulation device.
