Sort it out! Density‐gradient ultracentrifugation is used to separate single‐walled carbon nanotubes (SWNTs) of a single chirality. A “nanometal sinker” (AuCl 4 − 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”.
