Abstract:
1. A microfluidic device comprising: a body having a surface with a channel separating at least two first reservoirs, said channel disposed to have at least one focus node; at least one membrane in communication with the channel, proximate to said at least one focus node; a blank covering the channel and the at least one membrane; at least one second reservoir through the blank in contact with the at least one membrane, the at least one second reservoir in communication with the channel via the membrane; a first electrode positioned in one of the first reservoirs; and a second electrode positioned in the second reservoir wherein a potential applied to the first and second electrodes causes charged molecules to travel from the channel to the second reservoir through the membrane, wherein the channel, the membrane and the at least one second reservoir form a 3-level structure with the channel and at least one second reservoir separated by the membrane.
