Figure 4From: Application of functional quantum dot nanoparticles as fluorescence probes in cell labeling and tumor diagnostic imaging Generalized labeling of living cells using QDs. Confocal images of (A) HeLa and (B) D. discoideum cells. (C) Three-dimensional confocal projection of HeLa cells transiently transfected with the plasmid pECFP-Endo (encoding an endosome-specific reporter) and labeled with QD orange as above.[32].Back to article page
