Abstract
The present invention provides a device and methods of use thereof in concentrating a species of interest and/or controlling liquid flow in a device. The methods make use of a device comprising a fluidic chip comprising a planar array of channels through which a liquid comprising a species of interest can be made to pass with at least one rigid substrate connected thereto such that at least a portion of a surface of the substrate bounds the channels, and a high aspect ratio ion-selective membrane is embedded within the chip, attached to at least a portion of the channels. The device comprises a unit to induce an electric field in the channel and a unit to induce an electrokinetic or pressure driven flow in the channel.
