Hierarchical Porous Hollow Microsphere for Drug Release


Article Preview

Hierarchical porous titanate nanotube hollow microspheres were synthesized through a template-hydrothermal method. First, SiO2@TiO2 core-shell structure was synthesized, and then titanate nanotube hollow sphere was prepared via a simple hydrothermal method. The dimension of the cavity could be simply tuned by controlling the size of SiO2 spheres. These hollow microspheres exhibited a unique porous structure, in which the nanotube hollow microsphere had a two-fold storage system including the cavity of the hollow sphere and the nanotube capability. Further, the microsphere demonstrated an improved controlled releasing performance that the cavity was capable of giving a fast releasing, while the channel of the nanotube showed a slow releasing property. This facile template-hydrothermal method could be a generally strategy to prepare hollow nanostructures.
