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 regu-
lating 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 NPs could also detect DA and uric
acid(UA) simultaneously in the mixture without interference, indicating good selectivity and showing promising
potential in biosensing.
