Research on the properties and applications of molecules doped into sol-gel-derived silica matrices has expanded rapidly. This Account begins with a brief review of the use of the dopant molecules as probes of the changes that occur as the system evolves from the initial sol to the final xerogel during the formation of monoliths, thin films, and mesostructured films. Methods of deliberately placing desired molecules in specific regions of the mesostructure are discussed, and an application, energy transfer, is presented. Finally, encapsulation of biological molecules is examined, and two important aspects, stabilization of the biomolecules and applications as biosensors, are described.
