Abstract
Ferritin adsorbs on gold electrodes modified with a layer of 8-mercaptooctanoic acid. Cyclic voltammetry indicates the reduction of the ferritin layer at negative potentials followed by an anodic process in the return scan. However, a second cycle reveals that the latter signal is the anodic branch of a new electrochemical couple rather than the anodic branch of adsorbed ferritin. Control experiments including stirring the scan solution, electrochemical induction of iron release, and varying the scan rate strongly support the hypothesis that a dissolved iron species is released when ferritin is reduced, but its oxidized form adsorbs onto the SAM-modified electrode surface.
