Cytochrome c/Clay-Modified Electrode

Abstract

The direct electrochemical behavior of a small metalloprotein cytochrome c incorporated in a montmorillonite-modified membrane is described. The interaction of cytochrome c with the clay colloidal particles was investigated using electrochemical and spectrophotometric methods. The incorporated cytochrome c in the clay-modified membrane displayed a diffusion-controlled electrode process and still maintained its biological activity.
