First Claim
Patent Images
1. A method for forming an electrochemical test sensor, the method comprising the acts of:
- providing a base, a second layer and a plurality of electrodes, the base and the second layer assisting in forming a channel for receiving a fluid sample;
providing a pre-oxidized reagent material with an oxidizable species therein;
applying current to the pre-oxidized reagent material to oxidize the oxidizable species therein and form a modified reagent material having a reduced background current; and
placing the modified reagent material with the reduced background current on the test sensor in close relationship with at least one of the plurality of electrodeswherein the reagent includes a mediator and an enzyme.

Abstract
Systems and methods for electrochemically oxidizing components of a test-sensor reagent prior to deposition on a test sensor comprise at least a first electrode and a second electrode for contacting the test-sensor reagent. The first electrode and the second electrode may have hollow interior portions for contacting the test-sensor reagent to produce a modified test-sensor reagent having a reduced background current.
