Fig. 4From: Synthesis, Characterization, and Study of In Vitro Cytotoxicity of ZnO-Fe3O4 Magnetic Composite Nanoparticles in Human Breast Cancer Cell Line (MDA-MB-231) and Mouse Fibroblast (NIH 3T3)Magnetization curves measured at room temperature for A Fe3O4 NPs and B magnetic composite NPs (MCPs) between −10 and +10 kOe applied magnetic field. Obtained result shows that MCPs have retained superparamagnetic behavior with decrease in saturation magnetizationBack to article page
