Abstract
The present invention discloses a detection apparatus for fiber optics localized plasmon resonance and the system thereof. The detection apparatus for fiber optics localized plasmon resonance includes a light source, a fiber optics localized plasmon resonance detection apparatus and detection unit. The light source provides a light beam entering into the fiber optics localized plasmon resonance detection apparatus. The detection unit receives the light beam leaving the fiber optics localized plasmon resonance detection apparatus to generate a detection signal. The fiber optics localized plasmon resonance detection apparatus includes a fiber, a noble metal nano-particle layer and a filtering thin layer. The filtering thin layer is a porous material of which the pore diameter or the properties are selected according to the property of the substance to be detected so as to isolate the source of interference.
