Abstract
A self-referencing localized plasmon resonance sensing device and a system thereof are disclosed. The reference optical waveguide element is modified with a noble metal nanoparticle layer. The sensing optical waveguide element is modified with a noble metal nanoparticle layer, which is further modified with a recognition unit. The incident light is guided into the reference and the sensing optical waveguide elements to respectively generate localized plasmon resonance sensor signals. The reference and the sensing optical waveguide elements respectively have a calibration slope. The processor utilizes the calibration slopes to regulate the second difference generated by detecting with the sensing optical waveguide element. The processor utilizes a difference between the first difference, which is generated by detecting with the reference optical waveguide element, and the regulated second difference to obtain a sensor response.
