Glucose can be oxidized by oxygen when glucose oxidase are used as thecatalyst, therefore, the concentration of glucose can be measured by detecting the consumption of oxygen.For the detection of oxygen concentration, the ruthenium(Ⅱ) complex, Ru(bpy)3Cl2, were used as thefluorescence indicator and its fluorescence lifetime were detected by lock-in technology. The detectingrange of the sensor is 50 - 500 mg/dl and its response time is 30 seconds, showing that this kind of sensorsis possible to be used in clinical diagnosis and detection.展开更多
