Abstract
The present invention discloses a fiber-optic localized plasmon resonance (FO-LPR) sensing device and a sensing system thereof, the FO-LPR sensing system includes a light source, a FO-LPR sensing device and a detector, and the light source provides a light beam entered into the FO-LPR sensing device, and the detector generates a detected signal according to an emergent light from the FO-LPR sensing device. The FO-LPR sensing device includes an optical fiber, a noble metal nanoparticle layer and a filter film layer. The filter film layer is having a porous material, and the porous material comes with a pore diameter or a property selected according to a feature of a sample, while an interfering substance in the sample is isolated.
