ABSTRACT:
Spheres with a tetrahedral, octahedral and icosohedral geometry containing active compounds, wherein the spheres embrace the same volume as the fullerenes of the same symmetry, and are described by the formulas C.sub.360 N.sub.240 O.sub.24 U.sub.12, C.sub.1080 H.sub.300 N.sub.120 O.sub.24 U.sub.12, C.sub.144 N.sub.96 Cu.sub.14 and C.sub.432 H.sub.132 N.sub.48, their synthesis, the method of liberating the active compounds by irradiating the spheres to destroy the spheres such to release the active compounds, as well as possible uses for spheres filled with active compounds.
