Proposed transportation kinetics of QDs in ML-1 cells grown in the media with and without serum for 24 h. The models depict that the intracellular traffic kinetics of QDs in ML-1 cells grown with serum (Upper) is noticeably distinctive from that of ML-1 cells grown without serum (Bottom) after 24 h of QD treatment. (T1) indicates the transition of QDs from the endocytic vesicle towards the early endosome; (T2) indicates the transition of QDs from the early endosome towards the late endosome; (T3) indicates the transition of QDs from the late endosome to the lysosome.
