1. An enzyme electrode comprising:
- an electrode having a testing surface;
a transducing film covering the testing surface, which film comprises a cross-linked redox polymer network to which a redox enzyme is chemically bound, wherein the redox enzyme electrically communicates through the film with the electrode thereby transducing substrate flux to an electrical current; and
a polymeric film covering the transducing film and excluding from the transducing film proteins of molecular weights exceeding 5000 daltons.
