摘要:
Disclosed are controlled release compositions containing biologically active compounds incorporated into metal oxide glass having a porous matrix which is prepared by polymerizing one or more metal alkoxide monomers, optionally in the presence of a second metal alkoxide monomer. These compositions may be directly incorporated into the locus to be protected or may be applied to a structure in a coating.
