(20) The superparamagnetic iron oxide nanoparticle (SPION) and the super magnetic iron oxide nanoparticle (IONP) are commonly used contrast agents for the liver.
Of these, magnetic iron oxide nano-composites have been the most widely used support material [2] because they offer enormous surface area with more binding sites; this reduces the disadvantages of heterogeneous catalysis [24].
This synthesis approach seems to be especially interesting for the synthesis of nanoparticles for biomedical applications such as magnetic iron oxide [4], particularly in relation to the transference of the technology to the clinic and the need for standardization to avoid batch to batch inhomogeneity [5].
