1. An electrochemical biosensor having a layered structure, comprising:

  • a supporting layer having at least one surface;

    an electrode in contact with the at least one surface of the supporting layer, the electrode including carbon;

    a sensing layer comprising an analyte-responsive enzyme;

    a biocompatible layer disposed over the sensing layer of the electrode; and

    an interferant eliminating layer comprising a redox enzyme;

    wherein at least a portion of the sensing layer and the biocompatible layer allow diffusion of an analyte therethrough;

    wherein the electrode is connectable with a device; and

    furtherwherein the electrode is a working electrode, the working electrode comprises the analyte-responsive enzyme and a mediator, at least one of the analyte-responsive enzyme and the mediator is chemically bonded to a polymer disposed on the working electrode, and at least one of the analyte-responsive enzyme and the mediator is crosslinked with the polymer.
