Abstract

Multiple enzymes may be present in the active area(s) of an electrochemical sensor to facilitate analysis of analytes. The multiple enzymes may function independently to detect several analytes or in concert to detect a single analyte. One configuration includes a first active area and a second active area, where the first active area has an oxidation-reduction potential that is sufficiently separated from the oxidation-reduction potential of the second active area to allow independent signal production. Some configurations may have an active area overcoated with a multi-component membrane containing two or more different membrane polymers. Sensor configurations having multiple enzymes capable of interacting in concert include those in which a first enzyme converts an analyte into a first product and a second enzyme converts the first product into a second product, thereby generating a signal at a working electrode that is proportional to the analyte concentration.
