The interactions between CdSe quantum dots and yeast Saccharomyces cerevisiae: Adhesion of quantum dots to the cell surface and the protection effect of ZnS shell

The biological effects of CdSe and CdSe/ZnS QDs (ZnS: protection shell) on yeast Saccharomyces cerevisiae were investigated via microcalorimetric, spectroscopic and microscopic methods, clearly demonstrating a toxic order CdSe > CdSe/ZnS QDs.
