One-step approach to synthesize hollow mesoporous silica spheres co-templated by an amphiphilic block copolymer and cationic surfactant

Hollow mesoporous silica spheres (HMSSs) with an average diameter of 180 nm and magnetic-functionalized HMSSs have been successfully fabricated via a one-step facile route using the amphiphilic block copolymer polystyrene-block-poly (acrylic acid) (PS215-b-PAA12) and the cationic surfactant cetyl trimethyl ammonium bromide (CTAB) as co-templates.
