Abstract:
1. An apparatus for analyte detection comprising: a first chamber configured to store a test sample including analyte and microscaled components; a second chamber configured to store a reference solution; a pump and a plurality of injection chambers configured to introduce said reference solution and said test sample to a microfluidic separator; said microfluidic separator including a plurality of plates patterned with metal electrodes on at least one side and a plurality of internal channel structures having electrodes patterned on at least one internal surface wherein each of said plurality of internal channel structures is sandwiched between two of said plurality of plates which together form an array of microfluidic channels, said plate electrodes and said internal channel electrodes configured to provide opposing dielectrophoretic forces on said test sample which separates said test sample into said analyte and said microsealed components; a plurality of receiving microchannels adjacent said plurality of microfluidic channels configured to receive and remove said microscaled components; a third chamber configured to store said microscaled components when separated from said analyte; a condenser configured to capture said analyte once said analyte has passed through said microfluidic separator; and a sensor configured to detect said analyte.
