Abstract:
1. A check valve microfluidic transport device comprising: a microfluidic pump channel formed in a substrate for conducting a stream of fluid therethrough; a first check valve formed in the substrate having an inlet end and an outlet end, the inlet and outlet ends being disposed in spaced-apart relation, said check valve being in fluid communication with a first end of said microfluidic pump channel; an AC power supply; and a plurality of electrodes disposed proximate to said microfluidic pump channel, the plurality of electrodes electrically coupled to the AC power supply to provide an oscillating electric field to a fluid within said microfluidic pump channel, whereby cooperation between the check valve and oscillating electric field imparts a preferential flow direction to the stream of fluid by generating hydraulic pressures electroosmotically.
