| Abstract: | Using pure water as a mobile phase without any additional adjuvant,it was established that stable chromatography conditions separated water-soluble small gold nanoclusters capped by 2-mercaptosuccinic acid (MSA) monolayer in the size range of 1～5 nm by size exclusion chromatography (SEC).It was environment-friendly and easy to operate.The reproducibility was good. |
