将约3.5 nm的金纳米粒子(AuNSP)附着在镍盘电极上，研究了制备的AuNSP/Ni电极的电化学性质。由于AuNSPs的显著效应，用AuNSP/Ni电极记录的Fe(CN)的循环伏安曲线是可逆的，与用Au盘电极记录的循环伏安图几乎相同，而用Ni盘电极记录的循环伏安图没有可逆响应。尿酸和葡萄糖的电化学氧化也有类似的趋势。此外，AuNSPs还能抑制镍电极在碱性溶液中的氧化还原反应。
Gold nanoseed particles (AuNSPs) of ca. 3.5 nm were attached on a Ni disk electrode, and the electrochemical properties of the thus-prepared AuNSP-attached nickel (AuNSP/Ni) electrode were investigated. As a remarkable effect of AuNSPs, cyclic voltammograms of Fe(CN) recorded with an AuNSP/Ni electrode was reversible and almost identical to those recorded with an Au disk electrode, while a reversible response was not observed with a Ni disk electrode. The similar tendency was observed for the electrochemical oxidation of uric acid and glucose. Also, AuNSPs was proved to suppress the redox reactions of the Ni electrode in alkaline solutions.
