title: Fe3O4@organic@Au: core-shell nanocomposites with high saturation magnetisation as magnetoplasmonic MRI contrast agents.
abstract: The synthesis and characterization of core-shell Fe(3)O(4)@organic@Au nanoparticles displaying plasmonic behavior, high magnetism, and high relaxivity is presented. The incorporation of a thin organic layer between the two metals is crucial in maintaining the saturation magnetisation of the superparamagnetic core.
