Abstract

A new kind of nanorattle, composed of a Fe₃O₄/polymethyl methacrylate (PMMA) composite nanospherical core and mesoporous SiO₂ shell, has been successfully synthesized with the combination of a modified stöber method and a dual-template strategy, followed by alcohol dialysis. The nanorattles showed high efficiency in protein adsorption and separation.
