摘要
Stable cadmium sulphide (CdS) nanoclusters have been synthesised in non-ionic surfactant vesicles (niosomes). The nanocluster characteristics show strong dependence on the Cd2+ precursor concentration. At low precursor concentration, aggregates comprising fine nanocrystals of CdS with diameter 2 - 5 nm are formed. At high precursor concentrations, crystalline CdS nanoclusters (15 - 20 nm in diameter) are formed. Interestingly, these nanoclusters reside exclusively in the vesicular bilayer. Moreover, these nanoclusters are highly photoluminescent and exhibit cytotoxicity towards cancerous HeLa cells. As the vesicular bilayer mimics the cell membrane, the present work is extremely relevant to the use of the CdS nanoclusters for diagnostic and therapeutic purpose.
