Stable and biocompatible: The chemical composition of synthesized cationic thiolate-monolayer-protected gold nanorods was precisely determined. In vitro cell culture experiments showed no cytotoxicity of these nanorods, and the number of nanorods that were taken up by each cancer cell exceeded two million particles (see picture).
