Figure 3.

Spin-dependent cyclic voltammograms recorded for (A) Ala8 monolayers adsorbed over ferromagnetic substrates, (B) Ala8–CdSe hybrid structures under dark conditions, and (C) under light conditions. The voltammograms were obtained when the ferromagnetic cobalt (used as the working electrode) is magnetized either with its magnetic moment pointing UP (the solid blue line), or pointing DOWN (the solid red line). Voltammograms were recorded in Tris buffer containing 5 mM K₄[Fe(CN)₆]/K₃[Fe(CN)₆] at pH 9 at a scan rate of 50 mV s^–1, keeping the area of the ferromagnetic working electrode the same in all cases.
