Abstract:
1. A microfluidic separation device comprising: a first microchannel formed in a substrate, the first microchannel being defined by a bottom surface, a first wall, and second wall, the first microchannel including an upstream end and a downstream end; a plurality of magneto-hydro dynamic electrodes disposed on the first wall configured to apply a substantially uniform force oriented generally perpendicular to a long axis of the first microchannel; a plurality of dielectrophoretic electrodes disposed on the second wall opposite to the first wall configured to apply a substantially non-uniform force oriented generally perpendicular to a long axis of the first microchannel and opposite the force of the plurality of magneto-hydro dynamic electrodes; a voltage source connected to the plurality of electrodes on the first wall and the second wall; and a plurality of branch microchannels coupled to a downstream end of the first microchannel.
