Apparatus for pathogen detection
An apparatus for separating an analyte from a test sample, such as bacteria from blood components, based on their dielectric properties, localizing or condensing the analyte, flushing substantially all remaining waste products from the test sample, and detecting low concentrations of the analyte.

| description | An apparatus for separating an analyte from a test sample, such as bacteria from blood components, based on their dielectric properties, localizing or condensing the analyte, flushing substantially all remaining waste products from the test sample, and detecting low concentrations of the analyte. The module array includes a plurality of microfluidic channels with connecting microfluidic waste channels for directing undesired material away from the analyte. An electric field is applied causing a positive dielectrophoretic force to the analyte to capture the analyte. The electric field is applied to at least one electrode having a plurality of concentric rings or concentric arcs extending radially outwards from a center point, electrically connected to a voltage source such that when voltage is applied to the at least one electrode, the concentric rings or concentric arcs alternate in voltage potential. |
