Electrocatalytic Oxidation of Bovine Serum Albumin Mediated by Ruthenium(Ⅱ) Complexes upon Incorporation of ［Co(phen)_3］^3+ and SWCNTs

摘要: 应用循环伏安法、微分脉冲伏安法、荧光光谱法和扫描电镜等方法研究了［Co(phen)_3］^3+ (phen=1,10邻菲咯啉)和单壁碳纳米管(SWCNTs)促进［Ru(bpy)_2(tatp)］^2+ (bpy=2,2联吡啶, tatp=1,4,8,9四氮三联苯)在铟锡氧化物(ITO)电极上对牛血清蛋白(BSA)的电催化氧化. 结果表明，［Ru(bpy)_2(tatp)］^2+、BSA、［Co(phen)_3］^3+和SWCNTs间相互作用明显，BSASWCNTs的加入促进了［Ru(bpy)_

Abstract: ［Ru(bpy)_2(tatp)］^2+ (bpy=2,2bipyridine and tatp=1,4,8,9tetraazatriphenylene), singlewalled carbon nanotubes (SWCNTs) and ［Co(phen)_3］^3+ (phen=1,10phenanthroline) are successfully used to promote the electrochemical oxidation of bovine serum alb
