Silicones are extremely versatile materials that have found manifold apphcations in optical sensing of chemical species. Their high gas permeability, processability, optical transparency, composition tunabihty, resihency to biofilm adhesion and low cost, together with good chemical and thermal stability, have made silicones one of the polymer materials of choice to immobilize optical indicator dyes at the sensitive layer of fiber-optic gas sensors (mostly for monitoring). Silicones can also be used to manufacture optosensors for nonvolatile species, as long as they are modified with other materials to confer the required permeability to the indicator films. [Pg.339]
