Abstract: In the present study, we constructed a glassy carbon electrode covered with a biocompatible chitin-chitosan film that can modify functional substance. A carbon powder and a ferrocene were introduced into the composite film as the substances. The carbon powder improved the conductivity of the film, and the ferrocene had the function of an electron mediator. The ferrocene moieties were bound to the composite film using Schiff base between amino groups of the chitosan and ferrocenecarboxaldehyde. To examine the behavior of the ferrocene/carbon powder chitin-chitosan film, an electroactive dihydroxybenzene was selected. Dihydroxybenzene has three structural isomers, and the isomers are called pyrocatechol, resorcinol, and hydroquinone. Each electrode response differed, due to the difference of the permeability to the chitin-chitosan film. As a result, the responses of pyrocatechol were particularly improved. Therefore, the electrode constructed could contribute to measure catechol amines such as dopamine and adrenaline that are significant within organisms.
