1. An enzyme electrode for measuring D-fructose concentration is liquids comprising:

  • (a) a fructose dehydrogenase enzyme containing pyrrolo quinoline quinone cofactor;

    (b) a conductive polymer comprising a water soluble polyvinylpyridine complex of Os(bipyridine)2 Cl; and

    (c) an electron collector, said conductive polymer being chemically boned to said enzyme and adsorbed on said electron collector, said enzyme electrode being devoid of electron mediator save for said conductive polymer.
