一般說明

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。

應用

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。
