Abstract
A core-shell particle having an organic polymer core which is completely covered by a first inorganic oxide shell, wherein the first inorganic oxide shell has a silica (SiO2), an alumina (Al2O3), or a titania (TiO2); wherein the first inorganic oxide shell has a layer of a magnetic material which is disposed directly on the polymer core; further having a mesoporous second inorganic oxide shell, wherein the mesoporous second inorganic oxide shell covers the first inorganic oxide shell; wherein the mesoporous second inorganic oxide shell has silica (SiO2), alumina (Al2O3), or a titania (TiO2).
