Confocal laser scanning microscope images of in-vitro cellular uptake for Dox-PHMSN in presence of (A)) sucrose (inhibitor for clathrin dependent endocytosis); (B) Amilorin (inhibitor for macropinocytosis dependent endocytosis), (C) MβCD (inhibitor for caveolae dependent endocytosis) after 2 h of incubation. (D) Flow cytometry analysis for Dox-PHMSN in KB cells after 3 h incubation. Scale bar represents 20 μm.
