摘要：

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.
