Preparation Of Hierarchical Hollow Caco_3 Particles And The Application As Anticancer Drug Carrier

摘要

An objective in materials science of increasing importance is to construct inorganic architectures with hierarchically complex structures and optimized properties, which have great potential as agents in optical, electronic, and magnetic applications. Despite the various methods reported on the preparation of one-, two-, and three-dimensional crystal architectures, the organization of primary building units into hollow structures, though remaining a challenge for research activities on "crystal tectonics", still attracts much attention because of their promising applications in the encapsulation and controllable release of drugs, inks, flavors, and other chemical reagents. So far, some hard template-assisted approaches have been demonstrated to be most effective for the preparation of hollow structures, which typically include the coating of nanocrystals on the surface of templates and the removal of the templates afterwards.
