Abstract
A particle manipulation system uses a MEMS-based, microfabricated particle manipulation device which has an inlet channel, output channels, and a movable member formed on a substrate. The movable member moves parallel to the fabrication plane, as does fluid flowing in the inlet channel. The movable member separates a target particle from the rest of the particles, diverting it into an output channel. However, at least one output channel is not parallel to the fabrication plane. The device may be used to separate a target particle from non-target material in a sample stream. In the event that the microfabricated particle manipulation device malfunctions as a result of a particle of debris becoming lodged in the microfabricated particle manipulation device, the system may invoke a recovery algorithm, that includes vibrating the microfabricated particle manipulation device using a pulse train at a frequency near its mechanical resonance.
