Encapsulation of superparamagnetic Fe3O4@SiO2 core/shell nanoparticles in MnO2 microflowers with high surface areas

Superparamagnetic Fe3O4@SiO2 core/shell nanoparticles are caught by the microflowers made of MnO2 nanosheets with high surface areas. The hybrid particles exhibit multifunctionalities including superparamagnetism and strong adsorption associated with high surface areas.
