Pt nanoclusters were deposited in polypyrrole (PPy) nanowires by cyclic voltammetry method, fabricating a PPy–Pt nanocomposite on glassy carbon electrode (PPy– Pt/GCE). The electrocatalytic oxidation of Dopamine at PPy–Pt/GCE has been investigated. The sensor exhibited excellent electrocatalytic activity toward Dopamine oxidation. The effect of scan rate on Dopamine oxidation also was investigated.
