摘要

采用湿化学方法合成了金-石墨烯纳米复合材料。利用紫外可见光谱和透射电子显微镜对合成的金- g纳米复合材料进行了表征。通过固定葡萄糖氧化酶(GOx)，进一步将Au-G纳米复合材料滴铸在玻碳电极(GCE)上，用于葡萄糖的电化学检测。该传感器对葡萄糖在3 ~ 18 mM范围内具有良好的线性响应，线性系数为0.964。

Gold-graphene nanocomposite based ultrasensitive electrochemical glucose sensor

Gold-graphene (Au-G) nanocomposite has been synthesized by wet chemical method. Synthesized Au-G nanocomposite was examined under the UV-vis spectroscopy and transmission electron microscopy (TEM). Further Au-G nanocomposite was drop casted onto the glassy carbon electrode (GCE) by immobilizing glucose oxidase (GOx) into it for the electrochemical detection of glucose. Fabricated sensor demonstrates good linear response to glucose in the range 3 to 18 mM with linearity coefficient 0.964.
