Fig. 3From: A simple one-step electrochemical deposition of bioinspired nanocomposite for the non-enzymatic detection of dopaminea CV and b EIS of a GCE-PPy, b GCE-ErGO/PPy, and c GCE-ErGO/MWCNT/PPy in 5 mM K3Fe(CN)6 containing 0.1 M KCl. CV scan rate: 50 mVs− 1; impedance frequency range: 100 KHz to 0.1 HzBack to article page
