  • Doped sol-gel glasses for obtaining chemical interactions
    Patent number: 5824526
    Abstract: A sol-gel glass doped with one or more reagent that provides chemical interactions with diffusible solutes or components in an adjacent liquid or gas phase. The reagent(s), the solutes or the components can be any organic or inorganic compounds or materials of biological origin, including enzymes. The doped sol-gel glass in various forms is useful as an analytical test, chromatographic medium, sensor, catalyst or biocatalyst, electrode or enzyme electrode, and other detection devices.

  • Doped sol-gel glasses for obtaining chemical interactions
    Patent number: 5650311
    Abstract: A metod is proposed of obtaining a chemical interaction between at least one reagent trapped in sol-gel glass by doping it with the reagent(s), and diffusible solutes or components in an adjacent liquid or gas phase. The reagents, the solutes or the components can be any organic or inorganic compounds or materials of biological origins including enzymes. The doped sol-gel glass in various forms may be useful as analytical test, chromatographic medium, sensor, catalyst or biocatalyst, electrode or enzyme electrode, or other detection device.
