The synthesis of core-shell structured magnetic mesoporous silica particles with large pore sizes through a recently developed oil-water biphase stratification coating strategy was reported. The obtained nanoparticles exhibited spherical morphology, high surface area (347-430 m(2) g(-1)) and easily accessible large pore size. Significantly, the pore size of the silica shells can be finely controlled to range from 5.1 to 8.4 nm through tuning the coating conditions, including reaction temperature and the concentration of silica source in the upper oil phase. Such material might have great promising applications in drug delivery, catalysis and purification of water, etc.
