1. A sensor for detecting the presence or absence of an analyte, comprising:

  • a first solid state electrode having a surface having immobilized thereon a layer of a first redox-active moiety, wherein the first redox-active moiety has an oxidation potential and/or a reduction potential that is sensitive to the presence of the analyte; and

    a second solid state electrode having a surface having immobilized thereon a layer of a second redox-active moiety and a layer of a polymeric material adjacent to the layer of the second redox-active moiety, wherein the second redox-active moiety has an oxidation potential and/or reduction potential that is sensitive to the presence of the analyte.
