An amperometric glucose biosensor

Abstract

In this paper a miniature, enzyme based, amperometric glucose biosensor is described. A new technology was developed: an Al/sub 2/O/sub 3/ porous anodic film, acting as a cathalytical membrane, assures a better adhesion of the polymeric films which contain the embedded enzyme. The experiments have shown a good linearity (nonlinearity less than 2%) in the range 10-20 mM glucose concentration.
