| 摘 要： | 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.

| Abstract: | A novel deoxyribonucleic acid(DNA) functionalized single-wall carbon nanotubes(SWCNTs) electrode is preparated in this paper,in which the DNA is linked by forming covalent amide bonds between carboxyl groups of the nanotubes and amino groups at the ends of the DNA oligonucleotides.IR spectra for DNA-modified SWCNTs reveal DNA is covalently linked to the surface of SWCNTs.SEM micrographs illustrate the morphology and structure of the electrode modified by DNA-SWCNTs.Electrochemical characteristics of DNA-mod... |
