Fig. 8. Fluorescence microscopy analysis of the intracellular localization of red emitting NCs loaded into PC/DOTAP/PEG-liposomes (A) and PC/DOTAP-liposomes (B–C). HeLa cells were transfected with GFP-Rab5Q79L (green) for 24 h and treated with NC-liposomes for 6 h. Experiments were conducted with 40 μg mL^–1 of NC-liposomes containing 20 nM DDT-capped CdSe@ZnS NCs. Cells were then fixed and subjected to fluorescence microscopy analysis. For each image, magnifications of the boxed areas are shown in the respective lower insets.
