Amperometric glucose biosensors based on Prussian Blue- and polyaniline-glucose oxidase modified electrodes.

The properties of glucose sensors fabricated by immobilization of glucose oxidase in a layer of electrochemically deposited polyaniline were investigated. Selective amperometric glucose sensors were prepared by immobilization of glucose oxidase on a Prussian Blue-modified platinum electrode in a layer of polyaniline during a one-step electropolymerization procedure from phosphate buffer. The influence of ascorbic acid and acetaminophen was completely eliminated due to impermeability of polyaniline to these substances.
