Figure 7. Anticancer effect of gelatin/Fe3O4 porous scaffolds. Live/dead staining of MDA-MB-231-Luc cells cultured with gelatin/Fe3O4 scaffold discs via sitting (A), transwell (C), and adhesion (E) modes before and after AMF irradiation (live cells: green fluorescence, dead cells: red fluorescence). Quantified cell viability after culture with gelatin/Fe3O4 scaffold discs via sitting (B), transwell (D), and adhesion (F) modes before and after AMF irradiation. Cell viability was normalized to that cultured with gelatin porous scaffold without free Fe3O4 NPs before AMF irradiation. Data are the mean ± SD (n = 3). Significant difference: *P < 0.05, **P < 0.01, ***P < 0.001. N.S. : no significant difference.
