Properties and multifunctionality of Fe oxide @ Gold magneto-plasmonic heterostructures

Magnetic nanoparticles constitute nowadays a key component for the design of novel nanostructures with multi-fold functionalities. In particular magnetic - plasmonic heterostructures combine noble metals like Au and Ag with magnetic metallic or oxides moieties in a single nanostructure. These systems join simultaneously the optical absorption and all the opportunities provided by the plasmon resonance with all the chances offered by the magnetic counterpart. For these reasons, many potential applications, in particular in the biomedical field, are possible, like combined magnetic and photo thermal therapy, or dual magnetic and optical probe for cell imaging and drug delivery are now of great interest.
