(A) CV profiles of electrodes in response to 1.0 mM of H2O2: (a) PEDOT(BSA)/Pt, (b) AuNPs/PEDOT(BSA)/Pt, and (c) HRP/AuNPs/PEDOT(BSA)/Pt, respectively; (B) The linear correlations of peak current and concentration of H2O2 for the three corresponding electrodes, (a) PEDOT(BSA)/Pt; (b) AuNPs/PEDOT(BSA)/Pt and (c) HRP/AuNPs/PEDOT(BSA)/Pt, respectively. Each line was obtained from one single electrode with three experiments for every concentration of H2O2.
