Abstract
The invention provides methods for encapsulating nanometric particles inside of micro-sized crystals. An exemplary embodiment involves crystallizing a solution including nanometric particles, a micelle-forming material, a nonpolar dispersant for the micelle-forming material and a crystal-forming material to form crystal-encapsulated nanometric particles. Also provided are compositions or materials which include or are formed using the crystal encapsulated nanoparticles, such compositions and materials can include propellants, cosmetics, composite structures, energetics, and pharmaceutical compositions/materials.
