  • Sol-Gel based amonia optical sensor
    Lobnik, Aleksandra ; Majcen Le Marechal, Alenka ; Wolfbeis, Otto S.
    Ormosils were prepared in different ratios of tetramethoxysilane and organically modified sol-gel precursors of type R'Si(OR)3 and R'2Si(OR)2. pH indicators such as aminofluorescein have been ... incorporated into ormosils and the resulting materials were tested for their relative response to pH as well as to ammonia (dissolved ammonia at constant pH). R'2Si(OR)2-based layers are promising materials because of their high permeability to ammonia, and their impermeability to ions.
