The role of ligand coordination on the cytotoxicity of cationic quantum dots in HeLa cells

Nanoscale. 2013 Dec 21;5(24):12140-12143. doi: 10.1039/c3nr04037b.

Abstract

The effect of ligand structure on the cytotoxicity of cationic CdSe/ZnS quantum dots (QDs) was systematically investigated using mono- and bidentate ligands. Monothiol-functionalized QDs are more cytotoxic than dithiol-functionalized QDs.
