Fabrication of Functional Microcapsules
　Hollow microspheres (Microcalsules) are expected to medical and environmental applications such as DDS carrier, antibacterial materials, photocatalysts, absorbants and so on. Moreover, some ferromagnetic or radioactive ceramic microcapsules can locally cure deep-seated cancer. We attempt to fabricate such microcapsules through aqueous processing.
