Sol-gel technology is a versatile process used to synthesize materials at the nanoscale. It involves the transition of a system from a liquid "sol" into a solid "gel" phase. This method is particularly effective for producing nanoparticles, thin films, and porous structures. The process generally starts with the hydrolysis and condensation of metal alkoxides or metal salts, resulting in the formation of a colloidal suspension (sol) and subsequently evolving into a gel-like network.
