Superparamagnetic nanoparticles contain unique magnetic properties that differ from the bulk materials and are able to function at a cellular level due to their size, shape, and surface characteristics. These features make them attractive candidates for drug delivery systems, thermal mediators in hyperthermia, and magnetic resonance imaging (MRI) contrast agents. This review provides an up-to-date overview of the application of iron oxide nanoparticles in cancer diagnosis, drug delivery, treatment, and safety concerns related to these materials are considered, as well. Furthermore, the general principles and challenges of the magnetic behavior of nanoparticles in the field of oncology are also discussed. Firstly, the basic requirements for magnetic nanoparticles for biomedical applications are outlined. The close link between structure, shape, size, and magnetic characterization are described, which is considered essential for non-invasive imaging modality, innovative magnetic-driven nanocarriers, and treatment based on the overheating. In conclusion, investigation of the toxicity profile of novel nanoparticles is provided, as well. In the current review, the attention is focused on the role of magnetic nanoparticles, especially iron oxide nanoparticles in some bioapplications such as magnetic resonance imaging (MRI) contrast agents, targeted drug delivery, and magnetic hyperthermia systems.

Abstract: Iron oxide nanoparticles by the help of legitimate surface science have been broadly utilized tentatively in many living organism applications, for example magnetic resonance imaging (MRI), drug delivery, Repair of tissue, immunobiology, hyperthermia, detoxification of natural liquids, differentiate improvement between low contrast and high contrast tissues, and in cell partition and so on. What's more, these applications need exceptional nontoxic and biocompatible surface covering of the attractive particles to permit a targetable conveyance with molecular restriction in a particular territory. The general size of the colloid can be estimated ordinarily of surface covering and their resulting spatial course of action adjacent to the nanoparticles, it additionally assumes a critical job in bio-kinetics and bio-distribution of nanoparticles in the body. The kinds of surface coatings, for this sort of nanoparticles rely upon the kind of application and ought to be picked by remembering a specific application, regardless of whether it is gone for aggravation reaction or anti-cancer agents. In this paper, we examine the manufactured science, liquid adjustment and surface change of iron oxide nanoparticles, just as their utilization for biomedical applications
