Claim 10:
11. A method of making an electrochemical analyte sensor comprising the steps of:
disposing a working electrode on a base layer;
disposing an analyte sensing layer over the working electrode, wherein the analyte sensing layer detectably alters the electrical current at the working electrode in the presence of an analyte;
disposing a high-density amine layer comprising polymers having repeating amine groups directly on the analyte sensing layer; and
disposing an analyte modulating layer directly on the high-density amine layer, wherein:
the analyte modulating layer modulates the diffusion of analyte therethrough; and
the high-density amine layer is formed to comprise a first side in direct contact with the analyte sensing layer or the analyte modulating layer;
so that an electrochemical analyte sensor is made.
