A) CAs of thylakoid membrane modified GE/P(DTP-Ph-NH2) electrodes with different cyclic voltammetry cycles a)20, b) 40, c)60, d)80, e)100 applied for P(DTP-Ph-NH2) polymer coating. B) Cyclic voltammograms (CVs) of Cyt C, P(DTP-Ph-NH2)/Cyt and P(DTP-Ph-NH2)/Cyt C/ thylakoid membrane at a scan rate of 100mV/s in 10mM PBS pH 7.4. C) CA of P(DTP-Ph-NH2)/Cyt C/tilakoid membrane PBS. All CAs were performed upon a cyclic on-off illumination of light at an intensity of 6800 w/M2, applied potential; 0V (vs Ag/AgCl) in 10 mM pH 7.4 PBS.
