摘　　要：在玻碳电极上电沉积制备纳米铂颗粒,将葡萄糖氧化酶固定于纳米铂颗粒表面,并以二茂铁作为电子传递介质,在不同浓度葡萄糖溶液中进行循环伏安测试.实验结果表明,纳米铂颗粒能有效地提高葡萄糖氧化酶的催化活性,而增加对葡萄糖的电流响应.Platinum nanopartieles were prepared onto a glassy carbon （GC） electrode, and then glucose oxidase was immobilized on this prepared electrode to detect the concentration of glusose by eyelie voltammetry （CV）,in which ferroeene was employed as an electron transfer mediator. Results showed that the platinum nanoparticles could significantly enhance the catalytic activity of glucose oxidase and the current response of glucose.
