Abstract
A micromechanical particle sorting chip uses laser light directed through at least one of a reflective and refractive surface to come to a focus in an optically transparent layer. The laser light impinges on a particle of interest, causing it to fluoresce. Upon detecting the fluorescence, a micromemchanical actuator is activated, which directs the particle of interest into one of a plurality of possible exit paths.
