Abstract
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 stöber method and a dual-template strategy, followed by alcohol dialysis. The nanorattles showed high efficiency in protein adsorption and separation.
