Diameter-selective dispersion of double-walled carbon nanotubes by lysozyme

Nanoscale. 2011 Mar;3(3):970-3. doi: 10.1039/c0nr00831a. Epub 2011 Jan 25.

Abstract

We have utilized lysozyme to non-covalently functionalize and disperse double-walled carbon nanotubes (DWNTs) in aqueous solution. Lysozyme preferentially binds and disperses DWNTs with larger diameters. This is a facile and effective method to fractionalize and enrich DWNTs with certain diameters.
