The Problem of Purifying Single-Walled Carbon Nanotubes

Abstract

In search of purity: As technologies requiring the use of carbon nanotubes become more refined, the purity of the nanotubes becomes an ever-increasingly important factor. This Highlight not only takes a look at some attempts to improve the purity of single-walled carbon nanotubes (SWNTs) but also puts forward some new procedures to enhance their purity (the image shows SWNTs before (left) and after (right) one of the procedures described).
