Figure 8.

Cyclic voltammograms of cyt c electrostatically attached to carboxylic acid - terminated in the absence (dashed line) and the presence of 30 µM H₂O₂ after 3 (solid line) and 15 (dotted line) min incubation with H₂O₂. (a) Cyclic voltammograms of cyt c covalently attached to SAM at different concentrations of H₂O₂ in the absence (b) and presence of TOCL/DOPC liposomes (c). Cyt c was incubated with liposomes during 60 min and then H₂O₂ was added. The voltammograms were recorded after pre-incubation with H₂O₂ during 15 min under N₂. The voltammograms of cyt c without liposomes at pH 7.0 are shown for comparison on both figures (solid line). Scan rate 20 V/s.
