Magnetic nanoparticles coated with gold add new properties (inertness, protection of the magnetic core against oxidation, optical properties) to those of the magnetic particles, without modifying their superparamagnetic behavior. Gold shell is functionalized with poly(ethylene glycol)–thiol (PEG–SH) ligands having a carboxylic acid end group, which can be further used to immobilize covalently biomolecules by formation of stable amide bonds with primary amines.
