Modulation of the magnetic properties of gold-spinel ferrite heterostructured nanocrystals

[EN] The rational design of complex nanostructures is of paramount importance to gain control over their chemical and physical properties. Recently, magnetic-plasmonic heterostructured nanocrystals have been recognized as key players in nanomedicine as multifunctional therapeutic-diagnostic tools an...
