Patent ID: 7147441

Claim:
A microfluidic device comprising: at least one microfluidic channel having a length; at least two electrodes creating an electric field within the at least one channel wherein the field is perpendicular to the length of the channel by means of at least one anode and at least one cathode in the channel and opposite to each other; a magnetic field within the channel and perpendicular to the electric field and the channel; at least two solutions that are substantially immiscible, wherein at least one solution has a current carrying species, the current carrying species being capable of accepting at least one electron from the cathode and transferring the at least one electron to the anode such that the current carrying species does not accumulate upon the cathode or the anode and gaseous bubbles are not formed: wherein the current carrying species is a redox compound; wherein the electric field and the magnetic field induce the solution to flow in a direction perpendicular to both the electric field and the magnetic field.
