Fig. 2From: 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)TEM images of ZnO NPs, FNPs (Fe3O4 NPs), and MCPs with histogram showing relative size distribution. This illustrates formation of composite on nanoscale as suggested by XRD spectra comprising both NPsBack to article page
