Figure 4

(A) Schematic diagram for covalently tethered toluidine blue O (TBO) to the working electrode via a cysteine SAMs (L or D). (B) Spin-dependent cyclic voltammogram recorded for d-cysteine-toluidine blue O, and (C) cyclic voltammogram for l-cysteine-toluidine blue O on a 200 nm Ni/10 nm Au electrode. The working electrode was magnetized with its magnetic moment pointing either “UP” (dashed black curve) or “DOWN” (solid red curve). Reproduced with permission from ref (44).
