Abstract

Ferrocene-branched chitosan (CHIT-Fc) film electrodes were prepared from CHIT-Fc solution of variable pH to investigate the effects of film-forming solution pH on charge transport of the ferrocene. The redox behavior of CHIT-Fc polymer film electrodes was studied by cyclic voltammetry. The increase in both C∗D_ct^1/2 and film permeability with decreasing film-forming solution pH was observed. Incorporation of glucose oxidase (GOD) into these films demonstrated efficient electrical communication between the enzyme molecules and the electrodes for the oxidation of glucose. Optimal electrocatalytic response to glucose based on these films occurred at film-forming solution pH 2.8, which exhibited a high sensitivity of 77.5 μA·mM^{- 1}·cm^{- 2}.
