Abstract
A method of making an electrochemical sensor strip that includes: depositing a first electrode on a base; depositing a second electrode on the base; applying a first layer onto the first electrode; and applying a second layer onto the second electrode. The first layer includes an oxidoreductase and a mediator. The second layer includes a soluble redox species.
Claims28
An electrochemical sensor strip for analyzing an analyte in a test sample, the electrochemical sensor strip comprising:
- a base;
- a first electrode attached to the base;
- a first reagent layer disposed on the first electrode, the first reagent layer including an electroactive organic molecule and an oxidoreductase, the oxidoreductase being configured to facilitate a redox reaction of the analyte;
- a second electrode attached to the base;
- and
- a second reagent layer disposed on the second electrode, the second reagent layer consisting essentially of a redox pair with first and second soluble redox species configured to undergo redox reactions, wherein the redox pair is selected from a group consisting of an organotransition metal complex, a transition metal coordination complex, and mixtures thereof.
