Fig. 5From: Synthesis, characterization and biocompatibility of cadmium sulfide nanoparticles capped with dextrin for in vivo and in vitro imaging applicationIntracellular location of NPs Cds particles in HeLa cells. Control cells. a TEM micrographs in low magnification of an untreated HeLa cell. b Correspond to high magnifications of cells. Scales bars for A = 1 μm; B = 200 nm. Treated cells a and b correspond to TEM micrographs of different magnifications of the same cell. Images correspond to the apical face of the epithelial cell. Arrows show vesicles with electrondense particles corresponding to the CdS-Dx/QDs. Scale bars for A = 1 μm and B = 200 nmBack to article page
