Y. Kobayashi et al., Alternate deposition of cationic and anionic polymers for the improvement of response characteristics of glucose biosensor, ELECTROCH, 67(12), 1999, pp. 1147-1149
Organic thin films composed of cationic and anionic polymers were prepared
on the surface of glucose biosensor by an alternate deposition technique, t
o improve the response characteristics of the biosensor. The polymer thin f
ilm significantly suppressed the permeation of both glucose and ascorbic ac
id, which resulted in a suppression of ascorbate interference or an improve
ment of the dynamic range, depending on the arrangement of the enzyme and p
olymer layers on the electrode surface.
