Abstract

The invention comprises the design, synthesis, and characterization of mesostructured silica/block copolymer composite monoliths as controlled release systems. The controlled release function is based on the formation of mesostructured silica/block copolymer architectures via surfactant-templated sol-gel processing. Multi-layered or gradient monoliths are produced by layer-by-layer sol-gel processing to provide pulsed and programmed release characteristics. A simple, rapid route to prepare combinatorial compositional monolith libraries provides high-throughput synthesis and rapid screening of the release characteristics of the monoliths.
