Abstract
Multi-layered optical sensor films are disclosed. The sensor films include a first reflective layer, a detection layer over the reflective layer, and optionally a second reflective layer over the detection layer. The detection layer contains a hydrophobic, amorphous, substantially microporous, analyte-sensitive organosilicate composition. The analyte-sensitive organosilicate composition provides an optical change in the film upon analyte exposure.
