| 英文摘要 | Development of new nanostructured materials has shown high impact for improving the performance of chemical and biological sensors. In this work, we show that by controlling the dimensions of the gold flower microelectrode (GFME), it is possible to regulate detection sensitivity of a sensor for rapid analysis of chemical species. A 13-fold increase in sensitivity was achieved by enlarging the dimension of GFMEs from 70 to 330 mu m, whereas the response dynamics are dimension-independent, with the signal attaining saturation 20 s. Due to the intrinsic nanostructure on the microelectrode surface, our GFME exhibits excellent anti-interference property when applied to detect dopamine (DA) in the presence of 10-fold excess of ascorbic acid (AA). The regulable sensitivity, fast response dynamics, and excellent anti-interference property will make GFME an ideal sensing platform for biomedical applications. |
