Nanotechnology has attracted a great interest in recent years due to its unexpected impact on many areas of science and life, especially in engineering, biology and biomedicine Biologically synthesis of magnetic iron oxide nanoparticles -MIONPs- are among attractive nanomaterials, which have attracted the attention of many investigators owing to their ability of surface modification and high biocompatibility, as well as magnetic property. Because of the simple, cost-effective and environmentally-friendly production processes, biosynthesis is of paramount importance between chemical and physical technique of nanoparticles production. In the current work, we succeeded to synthesize MIONPs using a crocus sativus L. petal hydro-alcoholic extract. Created nanoparticles were characterized using FE-SEM, EDS and DLS methods.
