(A) EIS Nyquist plots of bare Pt electrode and Pt/MWCNTs in 1 mM Fe(CN)63−/4− solution containing 0.1 KCl, with frequency of 100 kHz to 0.1 Hz and amplitude of 0.01 V. (B) Cyclic voltammogram of 2.0 µg/mL doxorubicin on (a) bare Pt electrode and (b) Pt/MWCNTs in 0.1 M B-R buffer (pH 4.0) at scan rate of 0.1 V/s.
