1. A biosensor comprising:

  • an electrode having a surface;

    a polyionic polymer; and

    a modified enzyme formed by increasing the number of amine groups covalently bound to a glycosylated redox enzyme such that the pI of the modified redox enzyme is increased by at least 2 pH units with respect to the glycosylated redox enzyme;

    wherein the modified redox enzyme and the polyionic polymer are adsorbed or crosslinked on the surface of the electrode.
