... selected as the model specimen for cytotoxicityassessment, and the aims were to evaluate the cytotoxi-city of Fe3O4,OA-Fe3O4, and C-Fe and to elucida te the mechanisms of their cytotoxicities. ... which couldaffect the amount of MNPs entering the cells and further affect cytotoxicity. In our results, the surfacecharge of Fe3O4,OA-Fe3O4, and C-Fe were 14.4, 4.5, and 23.7 mV, respectively, ... data trend.MNPs influence on the cell cycle The effects of various concentrations (0.05, 0.1, and 1 mg/mL) of the three kinds of MNPs on cell cycle pro-gression and population distribution in...
