Silica layer-dependent leakage of cadmium from CdSe/ZnS quantum dots and comparison of cytotoxicity with polymer-coated analogues
The cytotoxicity of cadmium-containing quantum dots (QDs) is reportedly caused by released Cd2+ as well as other factors such as ligand, size, and surface modification. The tolerated concentration of QDs therefor...

Au/SiO2/QD core/shell/shell nanostructures with plasmonic-enhanced photoluminescence
A sol–gel method has been developed to fabricate Au/SiO2/quantum dot (QD) core–shell–shell nanostructures with plasmonic-enhanced photoluminescence (PL). Au nanoparticle (NP) was homogeneously coated with a SiO2 ...
