Novel multifunctional superparamagnetic and optical nanohybrids are fabricated for biomedical applications. This architecture involves a silica core surrounded by a thin shell of FePt that is further covered with an outer shell of gold. Polyethyleneimine was utilized as a linker to bridge the FePt shell with the gold shell, which allowed 3-nm gold nanoparticle seeds to be loaded and a uniform gold shell to be formed. These gold and FePt doubly coated silica nanoparticles take advantage of the tunable resonance absorption in the visible and near-infrared (NIR) ranges and can be controlled by using an external magnetic field, which makes them very promising candidates for future biomedical applications.
