Nanoparticles protect cells from apoptosis. Cells were treated with 200 μM H2O2 for 3 hr at 37°C to induce apoptosis. A) Negative and positive controls are shown (left). Cerium oxide (center) and platinum (right) nanoparticles are shown in panels B and C, respectively. Significant reductions in apoptosis are seen. (*P<0.01) (n=3)
