Fig. 2. Baseline subtracted cyclic voltammetries of Cyt-c before (orange) and after (blue) chemical treatment. (A) Cyt-c adsorbed on an NH₂-SAM electrode treated with 2 mM H₂O₂. (B) Cyt-c pretreated in solution with 2 mM H₂O₂ and subsequently adsorbed on an NH₂-SAM electrode. (C) Cyt-c pretreated in solution with 2 mM H₂O₂ in the presence of PE/PC liposomes, and subsequently adsorbed on an NH₂-SAM electrode. (D) Ex situ generated and purified SO-Cyt adsorbed on an NH₂-SAM electrode. All measurements were performed at 0.1 V s^–1 in 10 mM phosphate buffer, pH = 7.0. The insets are the voltammetric signals before background correction.
