22. A sensor for determining glucose concentration comprising:
- an optical fiber comprising a fluorescence chemical indicator, the chemical indicator system comprising a fluorophore that generates a fluorescence emission signal when excited by light and a glucose binding moiety to modulate the fluorescence emission signal, wherein the fluorophore is selected from the group consisting of a pyranine derivative, HPTS, an HPTS derivative, SNARF-1, SNARFL-1, a 6-methylquinolinium moiety, and TSPP, and wherein the extent of modulation of the fluorescence emission signal by the glucose binding moiety is related to the amount of glucose bound to the glucose binding moiety;
a light source; and
a detector. - View Dependent Claims (23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43)
- an optical fiber comprising a fluorescence chemical indicator, the chemical indicator system comprising a fluorophore that generates a fluorescence emission signal when excited by light and a glucose binding moiety to modulate the fluorescence emission signal, wherein the fluorophore is selected from the group consisting of a pyranine derivative, HPTS, an HPTS derivative, SNARF-1, SNARFL-1, a 6-methylquinolinium moiety, and TSPP, and wherein the extent of modulation of the fluorescence emission signal by the glucose binding moiety is related to the amount of glucose bound to the glucose binding moiety;
