MULTI-CONFIGURABLE SENSING ARRAY AND METHODS OF USING SAME

摘要

Disclosed herein are devices, apparatus, systems, methods and kits for performing immunoassay tests on a sample. The A sensing apparatus is provided for detecting a plurality of different target analytes in a sample. The apparatus may comprise an array of sensing devices provided on a substrate, each sensing device in the array comprising a working electrode having (1) semiconducting nanostructures disposed thereon and (2) a capture reagent coupled to the semiconducting nanostructures that selectively binds to a different target analyte in the sample. The apparatus may also comprise sensing circuitry that (1) simultaneously detects changes to electron and ion mobility and charge accumulation in the array of sensing devices when the capture reagents in the array of sensing devices selectively bind to the plurality of different target analytes, and (2) determines the presence and concentrations of the plurality of different target analytes in the sample based on the detected changes.
