  • Optical analyte sensor
    Patent number: 9891167
    Abstract: A waveguide sensor capable of direct, real-time detection and monitoring of analytes in the vicinity of the waveguide surface without requiring the tagging or labeling of the analyte, is described. Analytic and numerical calculations have predicted that by locally detecting either changes in the evanescent field or changes in the light coupled out of the waveguide as a result of the presence of the analyte, high detection sensitivity will be able to be achieved.

  • Method of fluorinating a halogenated organic substance
    Publication number: 20010049457
    Abstract: A method of fluorinating a halogenated organic substance comprising the steps of: introducing a germanium fluoride compound to a halogenated organic substance at a temperature between 250 and 320° C. to increase the fluorine content of the halogenated organic substance, thereby forming a fluorinated organic substance and a halogenated germanium compound, and separating the fluorinated organic substance and the halogenated germanium compound.
