解决掉！密度梯度超离心法用于分离具有单一手性的单壁碳纳米管。一个”纳米金属沉子”（AuCl 4-离子）吸附到特定的单壁碳纳米管上，并允许分离吸附的单壁碳纳米管和非功能化的单壁碳纳米管（见图）。（6，5）在称为”SWNT手性捕捞”的过程中，SWNT已成功地从制备的SWNT中分离。
Sort it out! Density-gradient ultracentrifugation is used to separate single-walled carbon nanotubes (SWNTs) of a single chirality. A" nanometal sinker"(AuCl4-ions) adsorbs onto specific SWNTs and allows the separation of adsorbed SWNTs and nonfunctionlized SWNTs (see picture).(6, 5) SWNTs have been successfully separated from as-prepared SWNTs in a process termed" SWNT chirality fishing".
