Then we modified carbon nanotubes (MWNT) with [Ru(bpy)2(NH2-phen)]2+ by chemical reduction method. According to fluorescence spectra analysis, atomic force microscopy and tunneling electron microscopic imaging, we confirmed that [Ru(bpy)2(NH2-phen)]2+ can be modified on carbon nanotubes by chemical reduction method and the adsorption rate is dependent on the denitrogenation rate of [Ru(bpy)2(N2-phen)]2+. And the adsorption rate was related to the reaction conditions such as reaction time, temperature, the concentration of ascorbic acid and sodium nitrite. We also used MWNT|[Ru(bpy)2(NH2-phen)]2+ to photochemically induce oxidative polymerization for Thionine chloride. Furthermore, we prepared ITO|[Ru(bpy)2(NH2-phen)]2+|MWNT|Nafion modified electrodes for detection of glucose, ascorbic acid, uric acid and NADH. The results showed this modified electrode’s sensitivity is better than non-modified electrode.奈米碳管三聯吡啶釕錯合物偶氮化修飾電極生化感測器原子力顯微術光敏劑5-氨基菲羅琳carbon nanotubeRuthenium trisbipyridinedenitrogenationmodified electodeBiosensoratomic force microscopyphotosensitizers5-amino110-phenanthroline
