In vitro inhibitory effects of fullerenol nanoparticles on cell migration. Typical images of scratch wound-healing assays (a), Transwell migration assay (c), and Transwell invasion assays (e) performed in MDA-MB-231 cells. The statistical results of scratch wound-healing assays (b), Transwell migration (d) and invasion assays (f). Scale bar = 200 μm in (a), and scale bar = 100 μm in (c) and (e). The inhibitory effect was normalized to control values, *P < 0.05, **P < 0.01
