A review of developments to date in the field of optical chemical sensors based on solgel- derived thin films is presented. The focus throughout is on those publications which have made a significant contribution to the area. The advantages and versatility of the solgel process are highlighted, with particular emphasis on the immobilisation of analytesensitive reagents. Possible sensing configurations are evaluated with respect to practicality and performance. Those problems, such as microstructural instability and leaching, which may restrict sol-gel sensors to short-term or disposable use are discussed and possible solutions are identified.
