我们报告的Au纳米电极的光刻制造，与几何表面积下降到160 nm × 1 μ m。使用电子显微镜和电化学通过可逆氧化还原对的扩散限制电流来验证电极的几何表面积。此外，电极的电化学活性表面积由空白伏安法中转移的电荷确定。我们相信这些可重复的纳米电极非常适合用作纳米电化学研究中的探针。(C)2011爱思唯尔有限公司版权所有。
We report the lithographical fabrication of Au nanoelectrodes, with a geometrical surface area down to 160 nm x 1 mu m. The geometrical surface area of the electrodes is verified using electron microscopy and by electrochemistry through the diffusion limited current of reversible redox couples. Moreover, the electrochemically active surface area of the electrodes is determined from the charges transferred in blank voltammetry. We believe these reproducible nanoelectrodes are well suited for use as probes in nano-electrochemistry research. (C) 2011 Elsevier B.V. All rights reserved.
