The contribution presents results of the research of an optical glucose sensor. The detection of oxygen depletion caused by glucose oxidation under glucoseoxidase catalysis was used in the glucose sensors. Fluorescence quenching of ruthenium complexes by oxygen was used for the oxygen detection. The complexes and enzyme were immobilized in inorganic-organic ORMOCER membranes. Developed fiber-optic sensors enable to detect glucose in concentrations up to 3 mmol/L and with response times of about 20s.
