Preparation of Deoxyribonucleic Acid Functionalized Single-wall Carbon Nanotubes and Study on Interaction with Artemisinin

单壁碳纳米管(SWCNTs)通过羧基和氨基形成酰胺共价键联上了DNA,从而制得DNA生物功能化的碳纳米管修饰电极.傅立叶红外光谱表明DNA共价结合在SWCNTs上,同时用SEM表征了研究电极的形貌.循环伏安法(CV)研究表明,DNA修饰电极反应过程属于扩散控制过程.与青蒿素的相互作用研究结果表明,SWCNTs上的DNA分子具有生物活性,且能与其它生物分子发生相互作用.
