采用电弧放电法制备了单壁纳米管。SWNT 通过在硝酸中纯化功能化。沿纳米管长度方向的羧酸 (-COOH) 官能团可与多种官能团衍生化。纳米管的平均直径为 1.4 nm±0.1 nm。研究了单壁碳纳米管在土壤中的迁移属性。
应用
利用羧基化的单壁碳纳米管修饰氧化铟锡 (ITO) 电极,制备了一种新型的电化学免疫传感器。羧基化的单壁碳纳米管进一步功能化,并用于研究连接的化学基团对寡核苷酸芘共轭物吸附的影响。有报道称利用功能化的 SWNT 设计了一种电化学 DNA 生物传感器。将其用于氯代羰基功能化 SWNT 的制备。 将其用于制备 SWNTs/(Pb,Zn)-磷酸盐玻璃复合结构,作为光传感器和光电流转换器的双重用途。详细研究了羧化 SWNT 与 Caco-2 的相互作用。

Single walled nanotubes were prepared by the electric arc discharge method. The SWNTs were functionalized by purifying them in nitric acid. The carboxylic acid (-COOH) functionality along the length of the nanotube can be derivatized with a variety of functional groups. The average diameter of the nanotubes is 1.4nm ± 0.1nm. Transport properties of the SWNTs in soil was studied.Carboxylated SWNTs were used to modify an indium tin oxide (ITO) electrode towards the fabrication of a novel electrochemical immunosensor. Carboxylated SWNTs was further multifunctionalized and were used in studying the influence of attached chemical group on the sorption of pyrene conjugates of oligonucleotides. An electrochemical DNA biosensor was reportedly designed using functionalized SWNTs. It was used in the preparation of the chlorocarbonyl-functionalized SWNT. It was used to fabricate SWNTs/(Pb, Zn)-phosphate glass composite structure for the dual use as light sensor and photocurrent converter. Interaction of carboxylated SWNT with Caco-2 was investigated in detail.
