We report stepwise changing of the magnetic behavior of iron oxide core−gold shell nanoparticles from superparamagnetic to permanent magnetism at room temperature upon stepwise biofunctionalization with luteinizing hormone and releasing hormone (LHRH) through a cysteamine linker. The observed permanent magnetism at room temperature in LHRH-capped gold nanoshells provides opportunities to extend fundamental investigations of permanent magnetism to other novel nanostructures and biofunctionalized nanogold architectures, simultaneously opening the way to newer applications, especially to those in biomedicine.
