技術說明

本發明揭露一種自我校正型定域電漿共振感測裝置及其系統。參考光波導元件以貴金屬奈米粒子層進行修飾。感測光波導元件以貴金屬奈米粒子層進行修飾，其中所述之貴金屬奈米粒子層以辨識元進一步修飾。入射光被導入參考光波導元件及感測光波導元件以分別產生定域電漿共振感測訊號。參考光波導元件及感測光波導元件分別具有校正斜率。處理器利用校正斜率調節由感測光波導元件檢測所產生的第二差值。處理器利用由參考光波導元件檢測所產生的第一差值及調節過的第二差值之間的差值，以獲得感測器響應。 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.
