N-halamine decorated mesoporous silica nanoparticles (mSiO2/halamine NPs) were prepared by coating mSiO2 NPs with poly (1-allylhydantoin-co-methyl methacrylate) (AH-co-MMA) by the aid of the radical polymerization, followed by chlorination treatment. The sterilizing effect on the bacterial strain is investigated by incubating Staphylococcus aureus (S. aureus) and Escherichia coli (E. coli). Results indicated that the mSiO2/halamine NPs had excellent antibacterial activity and no significant change occurred in antibacterial efficiency after five recycle experiments.
