- W2347029728 abstract "在pH=6.86磷酸盐缓冲溶液中,采用电化学(循环伏安法、微分脉冲伏安法和交流阻抗及数据拟合技术)、粘度测定、电子吸收光谱和溴化乙锭(EB)荧光分析法研究了[Cu(phen)(H2O)(L-Met)]+(phen=1,10-邻菲咯啉,L-Met=L-蛋氨酸)与小牛胸腺DNA的相互作用.结果发现中心铜离子在循环伏安图上呈现1对明显的准可逆氧化还原波.当加入一定量的DNA时,配合物的氧化还原峰电流明显降低,扩散系数减小,电化学反应电阻增大,电子光谱的最大吸收峰明显红移,产生明显的减色效应,同时,配合物也能较大程度地猝灭EB-DNA体系的荧光,说明[Cu(phen)(H2O)(L-Met)]+与DNA的作用较强,作用模式为部分插入作用." @default.
