Endocytosis and cellular concentration of Pt-MWNTS in non-small cell lung cancer cells. a Representative images of confocal microscopy showed the intracellular localization of Pt-NMWTS. (Pt-NMWTS is stained in red and the nuclei is in blue, scale bar = 50 μm). b The endocytosis of Pt-NMWTS was observed by flow cytometry at a time point of 0, 0.5, 1, and 4 h. c Relative intracellular uptake based on Pt was also quantitatively measured after 4 h treatment of Pt and Pt-NMWTS at 50 μM A549 and A549 DDP cells respectively. (n = 3, **P < 0.01 vs Pt.)
