Studies concerning the cyclic voltammetric (CV) behavior of biofunctional materials have been carried out. Three kinds of indicator electrodes were prepared by coating platinum disk electrodes with a polyacrylamide (PAA) membrane containing functional materials. Cells were then constructed with each electrode and an acetonitrile (AN) solution. The redox peak currents could be observed using the cell, in which the PAA membrane contained methylviologen. The different PAA electrodes containing a heme protein (cytochrome c, hemoglobin, or catalase) or a kind of iron ion containing antibiotics (bleomycin) showed different CV behaviors concerning the redox of oxygen. The difference in the voltammograms coinsided with a difference in the charge of the iron. The NADH and PQQ-containing PAA electrodes gave reduction currents proportional to the concentration of cyclohexanol in AN. The effects on the values of the current density of peaks due to the scan rate were also investigated in each case of the three different electrodes.
