High-purity separation of gold nanoparticle dimers and trimers

J Am Chem Soc. 2009 Apr 1;131(12):4218-9. doi: 10.1021/ja900809z.

Abstract

An effective method was developed for separating gold-nanoparticle clusters in high resolution; dimer and trimer samples were obtained with 95% and 81% purity, respectively.
