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. This focusing element may include cavities of variable cross section along the channel length. In addition, a filtering element may also be included upstream of the focusing element.
