Advances in nanotechnology have pushed forward the synthesis of a variety of functional nanoparticles (NPs) such as semiconductor quantum dots (QDs), magnetic and metallic NPs. The unique electronic, magnetic, and optical properties exhibited by these nanometer-sized materials have enabled a broad spectrum of biomedical applications. In particular, iron-oxide-based magnetic NPs have proved to be highly versatile deep-tissue imaging agents, having been incorporated into clinical applications due
