  • Graphene-conductive polymer-coated, paper-based nano-biosensor for cytokine detection
    Publication number: 20230068335
    Abstract: Sensors and methods of fabricating sensors for detecting an analyte, such as a cytokine are provided. A sensor includes a porous, hydrophilic substrate, throughout which a coating comprising a mixture of graphene and a conductive polymer is disposed. The sensor further includes a sensing area, at which the coating is functionalized with at least one molecule that provides for a binding interaction with the analyte, and a contact area. The contact area includes an electrode in operative arrangement with the sensing area to provide a signal indicative of an impedance.
