[0030] Embodiment 2: Referring to Fig. 3, the difference between the structure of the micro-Mei's interference biomolecular action probe and the probe structure of embodiment 1 is that there is a metal film 5 between the optical fiber cladding 1 and the biomolecular sensitive film 6, The material of the metal film 5 is gold, and the thickness of the metal film 5 is 30 nm, and the other is the same as the probe in the first embodiment.
[0031] Using the probe of the second embodiment, the difference between the corresponding embodiment of the sensing method and the sensing method of the first embodiment is that the light in the optical fiber cladding 1 is totally reflected at the interface between the optical fiber cladding 1 and the metal film 5 When surface plasmon resonance (SPR) will be generated, it will be attenuated and cause a phase change. The central wavelength of SPR attenuation, the attenuation amplitude at a specific wavelength and its phase change are affected by ...
