Figure 5: The effect of WO3 NPs on the mitochondrial membrane potential (MMP) in DPS and MCF-7 cells after 24 hours of incubation with WO3 nanoparticles (0.2–200 μg/mL). Cells were plated in 96-well plates and left overnight. Then, WO3 nanoparticles (0.2–200 μg/mL) were added, and after 24 hours, cells were stained with JC-1 dye.
