| Abstract: | The sensitivity and the portability are the primary characteristics of evanescent wave-based fiber optical biosensor. In order to improve its detection limit and field applicability, the evanescent wave strength of fiber probe and the compactness of the system are studied. Three kinds of system structure are analyzed, each of them corresponding to different research phase. A system of evanescent wave-based fiber optical biosensor with fiber bundle was designed and made as the transmission media of laser and fluorescence signal.The fluorescence signal was detected with this system. The structures future system and its characteristics were given out. |
