摘要

Using dextran as both reductant and stabilizing agent,nanopetals(ZnO-Au NPs) were easily synthesized and possessed a petal-like morphology.The feature structure and size of such ZnO-Au NPs were adjustable by regulating the amount of chloroauric acid(HAuCl4).Moreover,the electrochemical property of the obtained NPs was evaluated by being immobilized on the glassy carbon electrode(GCE),which performed both high sensitivity and stability in dopamine(DA) determinations.Furthermore,the as-prepared ZnO-Au N Ps could also detect DA and uric acid(UA) simultaneously in the mnixture without interference,indicating good selectivity and showing promising potential in biosensing.
