NANO-FLUIDIC FIELD EFFECTIVE DEVICE TO CONTROL DNA TRANSPORT THROUGH THE SAME

摘要

The present invention provides a nano-fluidic field effective device. The device includes a channel having a first side and a second side, a first set of electrodes adjacent to the first side, a second set of electrodes adjacent to the second side, a control unit for applying electric potentials to the electrodes and a fluid within the channel containing a charge molecule. The first set of electrodes is disposed such that application of electric potentials produces a spatially varying electric field that confines a charged molecule within a predetermined area of said channel. The second set of electrodes is disposed such that application of electric potentials relative to the electric potentials applied to the first set of electrodes creates an electric field that confines the charged molecule to an area away from the second side of the channel.

主权项

1. A method of controlling a charged molecule in a nano-fluidic field effective device, comprising:
applying a first electric field in a direction of a flow axis of a channel in said nano-fluidic field effective device to drive said charged molecule therethrough; and applying a second electric field to confine said charged molecule to a predetermined area within said channel.
