Highly Crystalline WO₃ Nanoparticles Are Nontoxic to Stem Cells and Cancer Cells

Figure 6

The effect of WO₃ nanoparticles on the nucleic morphology of DPS and MCF-7 cells. Cells were incubated with WO₃ NPs (0.2–200 μg/mL) and, after 24 hours, were stained with Hoechst 33342 dye to detect apoptotic morphology.
