29. A method of making a sensing device having a photoformed, gas-permeable membrane that is substantially impermeable to non-gaseous molecules and ions, comprising the steps of:
-
a.) applying an organosiloxane polymer comprising a silsesquioxane polymer having a bound labile moiety to a matrix overlaying a sensing surface to form a layer; b.) applying ultraviolet (UV) radiation to at least a portion of the layer to remove the labile moiety and to cause the organosiloxane polymer comprising a silsesquioxane polymer to form an adhered membrane overlaying at least a portion of the matrix; and c.) exposing the layer to a developer to selectively remove the organosiloxane polymer comprising a silsesquioxane polymer not exposed to the UV radiation.
