GLUCOSE SENSOR

摘要

A glucose sensor having an electrically insulating substrate, provided thereon, an electrode system comprising a working electrode and a counter electrode and, formed in contact with or adjacent to the electrode system, a reacting layer comprising glucose dehydrogenase with pyrroloqunoline as a coenzyme, wherein the reacting layer contains at least one additive selected from the group consisting of gluconic acid and salts thereof. The glucose sensor is a high performance sensor which is excellent in storage stability and exhibits improved response characteristics.
