Monolithic polydimethylsiloxane-modified silica composites prepared by a low-temperature sol–gel micromolding technique for controlled drug release
AbstractSol–gel derived multi-component silica composites are widely accepted as smart materials in orthopedic surgery as bone fillers and bioactive skeleton drug delivery systems. This paper discusses the effect of hydroxy-terminated polydimethylsiloxane (PDMS) (10, 20, 30 and 40% (w/w)) on the physicochemical properties of low temperature sol–gel processed polydimethylsiloxane/calcium phosphate/silica (PDMS-modified CaP/SiO2) composites. The micromolding technique was employed to obtain PDMS-modified CaP/SiO2 composites–monolithic granule-type formulations.
