Abstract

Organic thin films composed of cationic and anionic polymers were prepared on the surface of glucose biosensor by an alternate deposition technique, to improve the response characteristics of the biosensor. The polymer thin film significantly suppressed the permeation of both glucose and ascorbic acid, which resulted in a suppression of ascorbate interference or an improvement of the dynamic range, depending on the arrangement of the enzyme and polymer layers on the electrode surface.
