Confocal laser scanning microscope images of in-vitro cellular uptake for CPT & Dox·HCl loaded PHMSN in presence of (A) late endosome marker (green color) after 2 h and 4 h incubation. Blue and red color indicated the CPT and Dox, respectively. (B) Colozalization analysis in lysosomes with lysotracker green after 6 h, 10 h, and 16 h. Scale bar represents 10 and 5 μm, respectively. The cells were stained with late endosome.
