| 摘 要： | 将含糖基的简单两亲分子N-十八烷基麦芽糖酰胺(N-n-Octadecyl-D-maltonamide, NOMA)非共价修饰到单壁碳纳米管(SWNT)表面形成糖-碳纳米管复合体(NOMA-SWNT), 谱学和形态学结果表明, NOMA不仅能快速、高效地吸附到SWNT表面, 而且能有效地改善SWNT在水溶液中的分散性能. 以NOMA-SWNT管束为导通沟道构建了碳纳米管场效应管(CNTFET)器件, 检测了麦芽糖和伴刀豆凝集素蛋白(Con A)的特异性识别作用. 检测器件在每个修饰阶段的电学性能的变化证明了NOMA对SWNT的非共价糖基化修饰及用CNTFET来检测糖-凝集素特异性识别作用的可能性.

| Abstract: | Single-walled carbon nanotube(SWNT) was functionalized with N-n-octadecyl-D-maltonamide(NOMA),a simple sugar-containing amphipathic compound,by a method of noncovalent adsorption to form a NOMA-SWNT nanocomposite.The spectroscopic and morphology results show that NOMA could be rapidly and effectively adsorbed on the surface of SWNT without changing the native structure of NOMA and the structure properties of SWNT.Moreover,it was shown that the dispersion ability of SWNT in aqueous solution had a significant... |
