| Abstract: A Co3O4/ZnO acicular nanorod arrays (ANRAs) decorated acupuncture needle has been fabricated,which demonstrates a good performance for detecting the glucose.Firstly,the precursor Co (CO3)0.5(OH)·0.11H2O ANRAs were fabricated on the acupuncture needle through hydrothermal method.Thereafter,they could be completely converted to the Co3O4 ANRAs through annealing at 500℃ for 3 h in the air,then ZnO quantum dots (QDs) were decorated on the surface of Co3O4 ANRAs through dipping technique.It is found that Co3O4/ZnO ANRAs decorated acupuncture needle exhibits a good current response to glucose (2 264.27 μA·L·mmol-1·cm-2),meanwhile owning a fast response time (<4 s) and a detection limit as low as 0.311 μmol·L-1(S/N=3).Moreover,this acupuncture needle exhibited a high selectivity for glucose in human serum,against ascorbic acid and uric acid. |
