Magnetite Nanoparticles (Fe۳O۴) in Medicine (from Synthesis to Performance)

Nanotechnology has attracted significant attention due to its potential applications in medical science. Iron oxide nanoparticles have shown promising effects in various biomedical applications. In particular, magnetite nanoparticles (Fe₃O₄) are widely used due to their biocompatibility, high magnetic sensitivity, chemical stability, non-toxicity, high saturation magnetism, and low cost. Magnetite (Fe₃O₄) exhibits superparamagnetism because its size is reduced to about ۲۰ nm in the single-domain region, which is an essential feature for biomedical applications. This study investigates the application of magnetite nanoparticles (MNPs) in the field of biomedicine, focusing on different synthesis methods and surface functionalization materials. First, a brief introduction to the properties of MNPs, such as physical and magnetic characteristics, is provided. Due to the unique properties of MNPs, this review highlights several dominant synthesis methods and the effects of varying synthesis parameters. Encapsulation of MNPs with organic and inorganic materials is also discussed. Finally, the most common biomedical applications of MNPs are described. The aim of this review is to provide concise information to new researchers in this field, helping guide them in selecting appropriate synthesis techniques for MNPs to improve the efficiency of their work.
