Medical imaging is routine in the diagnosis and staging of a wide range of medical conditions. In particular, magnetic resonance imaging (MRI) is critical for visualizing soft tissue and organs, with over 60 million MRI procedures performed each year worldwide. About one-third of these procedures are contrast-enhanced MRI, and gadolinium-based contrast agents (GBCAs) are the mainstream MRI contrast agents used in the clinic. GBCAs have shown efficacy and are safe to use with most patients; however, some GBCAs have a small risk of adverse effects, including nephrogenic systemic fibrosis (NSF), the untreatable condition recently linked to gadolinium (Gd) exposure during MRI with contrast. In addition, Gd deposition in the human brain has been reported following contrast, and this is now under investigation by the US Food and Drug Administration (FDA). To address a perceived need for a Gd-free contrast agent with pharmacokinetic and imaging properties comparable to GBCAs, we have designed and developed zwitterion-coated exceedingly small superparamagnetic iron oxide nanoparticles (ZES-SPIONs) consisting of ∼3-nm inorganic cores and ∼1-nm ultrathin hydrophilic shell. These ZES-SPIONs are free of Gd and show a high T1 contrast power. We demonstrate the potential of ZES-SPIONs in preclinical MRI and magnetic resonance angiography.

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.
