Recent research has demonstrated that
coating the electrode surface with polymeric films is an attractive
approach for enhancing the power and scope of electrochemically modified
electrodes [1–۴]. Polymers such as polypyrrole, polythiophene and
polyaniline have been applied in electrochemical modification of
electrodes [5– ۹]. This new class of electrode material has been found
to improve the electrode sensitivity and selectivity, and to reduce
fouling effects in many applications [10,11]. On the other hand, the
electrochemical detection of carbohydrates, which are important in many
medical, biological and industrial applications, because of its
simplicity, selectivity and low cost [12,13], provides an alternative
approach to absorption and fluorescence detection methods in the
determination of carbohydrates in HPLC and FIA experiments. Various
authors have shown that carbohydrates and specifically glucose
