The sol - gel film showed the excellent chemical and electrochemical properties as well as kept the quality electrochemical activity of those immobilized redox molecules . the modified molecules took place the typical adsorption controlled electrochemical reaction , and furthermore , the modified methylene blue gave the obviously electrochemical catalytic affection on oxidation of nadh or reduction of hemoglobin if they were immobilized in the film meanwhile 同时以硅溶胶?凝胶膜为载体制得化学修饰电极，用sol - gel法在金电极上固定亚甲蓝、硫堇及茜素s ，发现固定于纳米溶胶?凝胶膜内的亚甲蓝和硫堇均有良好的电化学活性，对同时固定于膜内的nadh 、血红蛋白等生物分子产生显著的催化氧化还原作用。
Glucose biosensors were then constructed by these nanocomposites , and their electrochemical properties had been explored . secondly , the self - assembled nanocomposite was formed by mwnts and biopolymer , and was used to study the electrochemical properties of nadh . and finally , the modified electrode which was formed by immobilizing small molecular onto electrode surface , was used to detect dsdna in the solution 本论文首先,将多壁碳纳米管( mwnts )与纳米颗粒相结合,制备的纳米复合材料用于构建葡萄糖生物传感器,并研究了它的电化学性质;然后,将mwnts与生物聚合物自组装制备的纳米复合材料用于研究nadh的电化学性质;最后,本文还将小分子自组装固定在电极表面,用于测定溶液中的dsdna 。
