1. A method of making an amperometric electrode comprising the steps of:
- providing a substrate;
applying an electrode carbon ink to said substrate to form a working electrode;
said electrode carbon ink containing set amounts of graphite and carbon black;
cleaning said working electrode utilizing a gas plasma;
said gas plasma is a nitrogen gas plasma or an oxygen gas plasma; and
depositing a reagent layer to said working electrode after said cleaning step.

Abstract
A method of making and an amperometric electrode are provided. An electrode carbon ink is applied to a polymer substrate to form a working electrode. The substrate carrying the working electrode is placed in a gas plasma cleaner, such as an oxygen or nitrogen plasma, to clean the working electrode. A high radio frequency signal excites the gas plasma for a short exposure time in a range between 10 seconds and 30 seconds. Then a reagent layer is deposited to the plasma treated working electrode.
