We have synthesized various hollow inorganic nanoparticles by using micelles of several asymmetric block copolymers as a template. The hollow inorganic nanoparticles obtained include silica, tiatnia and calcium carbonate. We confirmed that our technique(J. Am. Chem. Soc., 129, 1534(2007)) is versatile and applicable to wide range of materials. Furthermore, the hollow inorganic nanoparticles were applied to drug delivery systems and lithium-ion batteries.
