Abstract:
1. An apparatus for sorting cells or particles by light induced dielectrophoresis (DEP), the apparatus comprising: (a) a fluidic chamber having a first surface and a second surface configured for retaining in the fluidic chamber a liquid containing a population of particles or cells to be sorted; (b) a photoconductive area on said first or said second surface configured for conversion of received light to a local electric field in the vicinity of the received light; (c) an inlet configured for receiving a sample liquid containing a population of particles or cells to be sorted; and (d) a plurality of outlet channels spaced-apart at relative distances in relation to the position of the photoconductive area of the fluidic chamber; (e) wherein the particles or cells are retrievable through specific outlet channels in the plurality of outlet channels as a function of response to the electric field; (f) wherein a specific outlet channel through which a said particle or cell is retrievable is indicative of relative magnitude of the response of the particle or cell to the electric field; and (g) an extraction port configured for manual extraction of a particle or cell from the fluidic chamber using a micropipette.
