Integration of New Sol-Gel Films Into Optical Chemical Sensors
CSEM has developed new sol-gel based sensitive layers enabling the optical detection of volatiles and dissolved analytes with enhanced performances. These sol-gel films exhibit a hierarchical nanoporous structure. Dedicated optical readers have been developed to interrogate the optical signal of the sensitive sol-gel patches. Applications of this technology, focusing yet on O-2, CO2, and pH detection, are illustrated with practical cases in aeronautics and environmental, health, and process monitoring.
