Inhibition of exocytosis increases the accumulation of MoS₂-based NSs. Schematic representation of exocytosis pathways in (a) HeLa and (b) MCF-7 cells. (c) HeLa and (d) MCF-7 cells were pretreated with Exo1 for 2 h, and then cells were incubated with fluorescent MoS₂-based NSs (10 μg/mL) for 3 h. Cytoplasmic fluorescence was measured by flow cytometer. (e) HeLa and (f) MCF-7 cells were incubated in the presence or absence of Exo1 for 2 h after fluorescent MoS₂-based NS treatment. After that, we renewed the culture medium with fresh DMEM and incubated the cells for 3 h. Cytoplasmic fluorescence was then measured by flow cytometer.
