Abstract
A MEMS-based particle manipulation system which uses a particle manipulation stage and a plurality of laser interrogation regions. The laser interrogation regions may be used to assess the effectiveness or accuracy of the particle manipulation stage. In one exemplary embodiment, the particle manipulation stage is a microfabricated, flap-type fluid valve, which sorts a target particle from non-target particles in a fluid stream. The laser interrogation stages are disposed in the microfabricated fluid channels at the input and output of the flap-type sorting valve. The laser interrogation regions may be used to assess the effectiveness or accuracy of the sorting, and to control or adjust sort parameters during the sorting process.
