使用各种阴离子、阳离子、非离子表面活性剂和聚合物将单个单壁碳纳米管（SWNT）悬浮在水介质中。对表面活性剂悬浮单个单壁碳纳米管的能力以及吸收和荧光光谱的质量进行了比较。对于离子表面活性剂，十二烷基苯磺酸钠 (SDBS) 具有最清晰的光谱特征。对于非离子体系，具有较高分子量的表面活性剂悬浮更多的SWNT材料并具有更明显的光谱特征。
Individual single-walled carbon nanotubes (SWNTs) have been suspended in aqueous media using various anionic, cationic, nonionic surfactants and polymers. The surfactants are compared with respect to their ability to suspend individual SWNTs and the quality of the absorption and fluorescence spectra. For the ionic surfactants, sodium dodecylbenzene sulfonate (SDBS) gives the most well resolved spectral features. For the nonionic systems, surfactants with higher molecular weight suspend more SWNT material and have more pronounced spectral features.
