Direct synthesis of CdS nanodots embedded in bovine serum albumin without external sulfur source for cell imaging†
Abstract
CdS nanodots (CNDs) were directly synthesized through a facile one-pot method using BSA as a template without adding an external sulfur source. The as-synthesized green fluorescent CNDs show much better water solubility and lower cell cytotoxicity, and can be directly used for live HeLa cell imaging without any further modifications.
