Nano Ferrites for Biomedical Applications

Superparamagnetic iron oxide nanoparticles have attracted attention due to their compatibility with various biomedical applications. The quantum confinement and increased surface area to volume ratio of the nanostructures alter their magnetic properties. There are several bottom-up techniques to synthesize superparamagnetic iron oxide nanoparticles; however, they offer certain limitations, like the existence of a secondary phase. The reaction parameters can be controlled to form pure-phase nanoparticles to increase their scope of applications in the field of medicine. Moreover, different applications demand different surface coatings of iron oxide nanoparticles.
