Abstract :
We synthesized a novel multi-fluorescence sensor which can respond to both pH and temperature. This kind of sensor was based on amino-polystyrene microbeads and two different fluorescent indicators (Rhodamine B and FITC) were applied simultaneously to synthesize the multi-sensor. Rhodamine B shows an excellent linear relationship between the relative fluorescent intensity and temperature while it is independent to PH. The relative fluorescence intensity of FITC can respond to both pH and temperature. We succeeded in the compensation of the pH sensitivity of FITC using temperature measurement by Rhodamine B.
