Fig. 3From: High-quantum yield alloy-typed core/shell CdSeZnS/ZnS quantum dots for bio-applicationsIn vitro cancer targeting with folic-acid-conjugated alloy QDs (alloy QDs-FA). a Schematic illustration of the interaction between alloy QDs-FA and human KB cells. b Fluorescence image of human KB cells with folic-acid-conjugated QDs (blue: nucleus of human KB cells; red: QDs). MQDs-FA and alloy QDs-FA were treated into human KB cells in a dose-dependent mannerBack to article page
