Abstract
Gold electrodes were modified with a polyaspartic acid thin film as a macromolecular recognition element for electrochemical reactions. The effect of electrode modification on the direct electron transfer reaction of cytochrome c was examined. Cytochrome c exhibited quasi-reversible redox reaction on the polyaspartic acid modified gold electrode. The ionic strength dependence and reactivity of the charged redox species suggested that the polyaspartic acid layer provided a matrix structure of charge groups which formed an attractive environment for the electron transfer reaction of cytochrome c.
