Abstract
An apparatus for extracting and concentrating bioagents within a continuously flowing fluid medium includes a flow channel fluid inlet, in which bioagents are concentrated from three dimensions to a two-dimensional transport layer in a preconcentration area. Traveling wave grids cause the preconcentrated bioagents to migrate to one side of the flow channel and then to an extraction port. Each of the traveling wave grids includes a substrate, a collection of closely spaced and parallel electrically conductive electrodes extending across said substrate, and a collection of buses providing electrical communication with the collection of conductive electrodes. A voltage controller provides a multiphase electrical signal to the collection of buses and electrodes of the traveling wave grids. Fluid exits through an outlet port.
