  • Optical measurement method for determining the pH of a medium using ageladine A as a fluorescent pH indicator
    Patent number: 8198098
    Abstract: An optical measurement method for determining a pH of a medium includes adding a fluorescent pH indicator to the medium. The pH indicator is based on naturally-obtained or synthesized ageladine A. The pH indicator is irradiated with light of at least one wavelength so as to provide fluorescence excitation of the pH indicator. An emitted fluorescence intensity of the pH indicator is detected as a measure for the pH of the medium.
    Type: Grant
