Cell proliferation assay of colon cell lines treated with BMNP and FeCl3. The cell lines HT29 (A), SW480 (B), HCT15 (C), MC38 (D), T84 (E), and CCD18 (F) were exposed to increasing concentrations of Fe from 0.05 to 100 µg/mL from FeCl3 and BMNPs for 72 h. The graphs represent the percentages of proliferation of all the cell lines obtained using the SRB assay. Data represent the mean values ± SD of triplicate cultures.
