摘要：

In this paper the theoretical base and experimental results of a new class of fiber optical supported surface plasmon resonance spectroscopy (SPRS) transducer is given. Surface plasmons were excited by polychromatic light, and the resonant excitation is detected as an intensity minimum in the measured spectra at certain wavelengths. The excitation takes place at the end zone of a multimode fiber coated with a thin surface plasmon resonance supporting metal layer. As examples for the large application field of this transducer a fiber optical immunosensor for the detection of antibodies against bovine serum albumin and a gas sensor for remote detection of tetrachloroethene was constructed and tested successfully. The sensors were constructed following the theoretical predictions for an optimal performance.
