Outline of Final Research Achievements

We have established the preparation method of silica nanocapsules entrapping assemblies of functional molecules.The assembly nanoparticles of the functional molecules were prepared through the injection method, which gave a colloidal dispersion of the molecular assemblies. Homogeneous silica layers formed on the molecular assemblies by the addition of silica source. Homogeneous catalysts such as metal complexes and enzymes were entrapped in silica layer through our method. They served as a catalyst of chemical reactions. The wrapping of the catalysts with silica layer make it easier to recovery them. We think these results are beneficial in industrial applications.
