H40-PLA NPs were uptaken through endocytosis by the cells. Representative images of MCF-7 cells, DsRed-Rab5 transfected MCF-7 cells and DsRed-Rab7 transfected MCF-7 cells were treated with 100 μg/mL coumarin-6-loaded H40-PLA NPs for 2 h. For lysosome detection, the MCF-7 cells were treated with 100 μg/mL coumarin-6-loaded H40-PLA NPs for 2 h, and then co-treated with Lyso-Tracker Red probes for 30 min. The above images are the enlarged ones in the white collar on the underside images. Scale bars: 10 μm.
