Figure 3

Panels A – C depict the uptake of particles in cultured U87 glioblastoma cells. Panel A is the phase contrast image, while B is the fluorescence acquisition. Panel C shows the merge and it can be seen that significant proportion of the cells have internalized the targeted QD liposomes. In comparison panels D – F show the uptake of non-targeted QD liposomes by U87 cells. The merge of D and E, denoted by panel F, reveals that endocytosis of the non-targeted QDs resulted in considerably less internalization than was the case with targeted particles.
