ABSTRACT

One of the most important fields of scientific study in the modern era has been deemed to be nanoscience. Due to their unique features, using nanoparticles in biological applications offers several benefits. The magnetic nanoparticles (MNPs) of iron oxide, among other types, have intrinsic properties successfully used for biomedical applications such as bioimaging, drug delivery, chemotherapy, magnetic hyperthermia, biosensors, and regenerative medicine. The size and shape of nanostructures primarily influence superparamagnetic iron oxide nanoparticles’ physical and chemical characteristics. These properties are important for improving the properties of MNP, and they can be controlled with the appropriate synthesis methods. On the other hand, by properly modifying and functionalizing the surface of iron oxide nanoparticles, the mechanical and physicochemical properties, stability, biocompatibility, and surface activity of MNPs can all be greatly improved. This chapter focuses on standard fabrication techniques, advantageous surface coatings in light of the key characteristics needed for their biomedical use, and novel applications.
