description: In this study, <b>graphene oxide</b> was electrochemically deposited and reduced on a <b>graphite sheet</b>. The electrode surface morphology was studied by scanning electron microscopy. The performance of the modified electrode in detecting dopamine was investigated. The results indicate that the <b>electrodeposition</b> of <b>reduced graphene oxide</b> onto the electrode surface increases the <b>dopamine</b> oxidation current, decreases the overpotential, and reduces the charge transfer resistance. The efficiency of <b>dopamine detection</b> by this modified electrode was evaluated using <b>cyclic voltammetry</b>, <b>differential pulse voltammetry</b>, and <b>electrochemical impedance spectroscopy</b>. The effects of ... Read more
