用四氯金酸盐改变单壁碳纳米管（SWCNT）的密度使得能够对SWCNT进行手性分选。在这项研究中，我们详细研究了单独增溶的（n，m）-单壁碳纳米管的密度变化行为所造成的四氯金酸使用密度梯度离心和可见近红外吸收光谱。（7，5）-、（8，4）-和（8，3）-单壁碳纳米管的密度与相应单壁碳纳米管的氧化程度之间呈线性关系。虽然（6，5）-SWCNT几乎不被四氯金酸盐氧化，但它们的密度通过添加四氯金酸盐而增加。
Density change of single-walled carbon nanotubes (SWCNTs) with tetrachloroaurate enables chirality sorting of the SWCNTs. In this study, we examined in detail about the density change behavior of individually solubilized (n,m)-SWCNTs caused by tetrachloroaurate using density gradients centrifugation and vis-near IR absorption spectroscopy. The (7,5)-, (8,4)- and (8,3)- SWCNTs showed a linear relationship between the density and the degree of the oxidation of the corresponding SWCNTs. Although the (6,5)-SWCNTs was hardly oxidized by tetrachloroaurate, their density increased by the addition of tetrachloroaurate.
