(a). MTT assay data of OA-C- Fe3O4 nanoparticles (0–60 µg/mL) with HCT 116. Each value signifies the mean ± SE of three trials, n = 3, (*p < 0.05, **p < 0.01, ***p < 0.001) compared with the control; (b) MTT assay data after 10–40 min blue light exposure (after 20 µg/mL OA-C- Fe3O4 treatment); (c) MTT assay data of OA-C- Fe3O4 nanoparticles (0–60 µg/mL) with HEK-293.
