Abstract
Sol-Gel is formed by conversion of liquid precursor into a sol and then to a gel. This technique is a common process for forming porous materials via solidification from a real solution phase. Preparation of homogenous solution, hydrolysis, gelation, drying, densification are major steps in sol-gel formation. Sol-Gel derived materials include glasses, ceramics, and nanoparticles, each offering unique properties and characteristics tailored to particular applications. Sol-Gel offers a distinct pathway for creation of many new and conventional nanomaterials that had been improved by combustion or hydrothermal treatment. This review highlights sol-gel process, steps involved in preparation and applications in medicine.
