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.

Magnetic iron oxide nanoparticles are promising material for various biological applications. In the recent decades, magnetic iron oxide nanoparticles (MNPs) have great attention in biomedical applications such as drug delivery, magnetic resonance imaging (MRI) and magnetic fluid hyperthermia (MFH). This review focuses on the colloidal stability and monodispersity properties of MNPs, which pay more attention toward biomedical applications. The simplest and the most promising method for the synthesis of MNPs is co-precipitation. The biocompatible MNPs are more interested in MRI application. This review also apportions synthesis, characterization and applications of MNP in biological and biomedical as theranostics and imaging.
