ABSTRACT:
A micromechanical particle sorting chip uses an actuator divided into two parts to direct a component of interest into one of a plurality of possible exit paths, based on detection of a fluorescent signal emanating from the component of interest. The two-part actuator may include a force-generating portion and a microactuator portion. The microactuator portion may be disposable, whereas the force-generating portion may be reuseable. By bringing the force-generating portion into proximity to the microactuator portion, the microactuator is induced to move, thereby separating the component of interest from the rest of the fluid stream. The force-generating portion and the microactuator portion may be optimized and fabricated separately, thereby leading to faster, more reliable and less expensive particle sorting.
