In this study, iron oxide nanoparticles (Fe3O4, IONs) were manufactured by using calcination of organic nanoparticles containing iron oxide precursor. The prepared IONs can be applied as MRI contrast agents, drug delivery system (DDS) and so on. The characteristics of the IONs prepared at varying concentrations of alginate and iron chloride (Iron(Ⅱ), Iron(Ⅲ)), and the calcination temperature were observed. The size of the IONs was analyzed through ELS, and the image of the particles was examined through TEM. Elemental analysis of IONs was also performed. XRD was performed to determine the structure of IONs. Magnetic susceptibility of IONs was measured by VSM.
