• A new kind of nanorattle, composed of a Fe 3 O 4 /polymethyl methacrylate (PMMA) composite nanospherical core and mesoporous SiO 2 shell, has been successfully synthesized with the combination of a modified stber method and a dual-template strategy, followed by alcohol dialysis. The nanorattles showed high efficiency in protein adsorption and separation. Novel high-magnetization superparamagnetic silica nanorattle with a Fe 3 O 4 /PMMA composite nanospherical core and periodic mesoporous SiO 2 shell. The nanospheres allow closer packing of Fe 3 O 4 nanoparticles, increasing the magnetization saturation value and avoiding leakage of free Fe 3 O 4 nanoparticles.
