Abstract: An ionic liquid-channel charge-coupled device that separates ions in a liquid sample according to ion mobility characteristics includes a channel having an inner wall that has a matrix liquid disposed within. An insulating material surrounds the channel, and an introduction element introduces a liquid sample into the channel. The sample is preferably a liquid solution that has at least one ionic specie present in the solution. The device further includes a gating element that establishes at least one charge packet in the channel in response to an externally applied input signal, and a transport element that induces the charge packet to migrate through the channel. The gate element can be a plurality of spaced-apart, electrically conductive, gate structures that are alternately disposable between a high voltage state and a low voltage state. The transport element further includes an application element that applies a variable voltage to the gating element. This application of voltage induces the charge packets to form under the gate structures and, when the voltage applied to an adjacent gate has a higher potential, induces the packet to migrate through the channel in that direction.

The sample is preferably a liquid solution that has at least one ionic specie present in the solution. The device further includes a gating element that establishes at least one charge packet in the channel in response to an externally applied input sisal, and a transport element that induces the charge packet to migrate through the channel. The gate element can be a plurality of spaced-apart, electrically conductive, gate structures that are alternately disposable between a high voltage state and a low voltage state. The transport element further includes an application element that applies a variable voltage to the gating element.
