研究了在聚苯乙烯衬底上制备的Au纳米颗粒薄膜作为一种新型电极材料。薄膜由不同尺寸(2-50 nm)的Au颗粒和粘结剂分子(甲硫醇、丁硫醇、戊硫醇、己硫醇和庚硫醇)在衬底上直接形成。该电极允许人们监测仅在纳米颗粒上发生的反应，并以这种方式成功地检测到由过氧化氢和有机胺等小分子产生的催化电流。
Au nanoparticle films prepared on a polystyrene substrate were studied as a new electrode material. The films were formed from Au particles with different sizes (2–50 nm) and binder molecules (methanethiol, butanethiol, pentanethiol, hexanethiol and heptanethiol) on the substrate with a straightforward procedure. The electrode allows one to monitor reactions occurring only on the nanoparticles, and the catalytic currents resulting from small molecules such as hydrogen peroxide and organic amines were successfully detected in such a manner.
