提出了一种新的工艺，用于制造Au纳米盘电极阵列与控制盘电极分离。该过程通过确保充分的盘分离有效地克服了盘间扩散层重叠的问题。使用SiC模具，铝基板上压印有理想有序的图案，该图案具有在规定位置处的特征，然后选择性地蚀刻为用于Au沉积的通孔。所制备的Au盘电极阵列表现出S形伏安行为，表明该阵列有效地作为单个纳米电极的集合。(C)2004年电化学学会。
A novel process for the fabrication of Au nanodisk electrode arrays with controlled disk electrode separation is proposed. This process effectively overcomes the problem of overlapping diffusion layers around interdisks by ensuring sufficient disk separation. Using an SiC mold, an aluminum substrate was imprinted with an ideally ordered pattern with features at prescribed sites that were then selectively etched as through-holes for the deposition of Au. The fabricated Au disk electrode arrays exhibited sigmoidal voltammetric behavior, indicating that the array functioned effectively as an ensemble of single nanoelectrodes.
