Patent ID: 8877037

Claim:
A multi-phase analyte insensitive electrode (AIE) for use in an electrochemical sensing device for measuring an analyte in a sample, the AIE comprising (a) an electrolytic layer; (b) an electrically conductive component electrically connected to the electrolytic layer, the electrically conductive component further comprising a composite material comprising a binder and an electrically conductive material comprising at least one of graphite, glassy carbon, multi-walled carbon nanotubes (MWCNTs), single-walled nanotubes (SWNTs), boron-doped diamond, and any combination thereof; (c) a redox active material capable of being at least one of electrically oxidized and electrically reduced, the redox active material being dispersed in at least one of the electrolytic layer, the conductive component, and the composite material; and (d) a conductive physical barrier positioned so that it is interposed between the electrolytic layer and a sample when the electrode is in contact with the sample, and that physically separates the electrolytic layer from the sample.
