Figure 3From: Enhanced anticancer activity of DM1-loaded star-shaped folate-core PLA-TPGS nanoparticlesCLSM images of MCF-7/HER2 cells after determined time of incubation with coumarin 6-NPs. The coumarin 6-loaded nanoparticles were green, and the cell nuclei were stained by DAPI (blue). The cellular uptake was visualized by overlaying images obtained respectively from the EGFP filter and DAPI filter: (A) After 12 h incubation with coumarin 6-NPs, (B) after 24 h incubation with coumarin 6-NPs, and (C) after 36 h incubation with coumarin 6-NPs. Scale bar 10 μm.Back to article page
