Switching an O2 sensitive glucose oxidase bioelectrode into an almost insensitive one by cofactor redesign

Abstract

In the 5–8 mM glucose concentration range, of particular interest for diabetes management, glucose oxidase bioelectrodes are O₂ dependent, which decrease their efficiencies. By replacing the natural cofactor of glucose oxidase, we succeeded in turning an O₂ sensitive bioelectrode into an almost insensitive one.
