Magnetic nanoparticles, including metallic (iron, cobalt), alloy (iron–platinum, iron–cobalt) or iron oxide (magnetite, maghemite or ferrite phase) exhibit a singular property called superparamagnetism. The nanoscale size of these nanoparticles makes their superparamagnetic properties both size- and shape-dependent. In addition to these two parameters, the presence of magnetic interactions between nanoparticles induce a new magnetic state. This is especially true for multicore magnetic nanoassemblies. Multicore nanoassemblies include magnetic nanoparticles embedded or decorating organic, polymer or biological matrices. In these structures, the number of interacting nanoparticles and the distances between them can lead to two new magnetic orders: superspin glass and super(ferro/ferri)-magnetic state. In the first case, the nanoparticles are in dipolar interactions, which induces a strong spin-frustation. The second case is characterized by nanoparticles in exchange coupling, causing a collective magnetic order. This Special Issue of Nanomaterials, “Multicore Magnetic Nanoparticles for Biomedical Applications”, aims to highlight how interparticle interactions affect the properties of multicore nanoassemblies labeled for biomedical application. The topic covers a wide range of biomedical applications, including but not limited to magnetic fluid hyperthermia, magnetic resonance imaging, on-demand drug delivery or magnetic particle imaging. The format of the expected contributions includes communications, articles or reviews.

Abstract: Nanoassemblies encompass a large variety of systems (organic, crystal, amorphous and porous). The nanometric size enables these systems to interact with biological entities and cellular organelles of similar dimensions (proteins, cells, tumor …). Over the past 20 years, the exploitation of their singular properties as contrast agents has led to the improvement of medical imaging. The use of nanoprobes also allows the combination of several active units within the same nanostructure, paving the way to multi-imaging. Thus, the nano-object provides various additional information which help simplifying the amount of clinical procedures. In this review, we are interested in the combination between fluorescent units and magnetic nanoparticles to perform dual mode magnetic resonance imaging and fluorescent imaging. The effect of magnetic interaction in multicore iron oxide nanoparticles on the MRI contrast agent properties are investigated.
