Patent ID: 7399398

Claim:
An electrokinetic device comprising: a solid substrate, wherein the solid substrate comprises a fluid path formed in the solid substrate; a plurality of pumping conduits in the fluid path, each having a first end and a second end and comprising a porous dielectric material; a first electrode, wherein the first electrode is in electrical communication with the first end of each of the pumping conduits when the fluid path contains a transport fluid in which electroosmotic flow can be induced; a plurality of conducting conduits in the fluid path, each having a first end and a second end, wherein the first end of each of the conducting conduits is in fluid communication with the second end of one of the pumping conduits; a second electrode in electrical communication with the second end of each of the pumping conduits when the fluid path contains the transport fluid; and a cover on the solid substrate which seals the fluid path.
