| 摘要 |
The present invention discloses a self-referencing fiber-optic localized plasmon resonance sensing device and a system thereof. The self-referencing fiber-optic localized plasmon resonance sensing device comprises a reference optical fiber, a sensing optical fiber and a carrier. The reference optical fiber is modified with a first noble metal nanoparticle layer, and receives an incident light to generate a first localized plasmon resonance sensor signal. The sensing optical fiber is modified with a second noble metal nanoparticle layer. The second noble metal nanoparticle layer is further modified with a molecular or biological recognition unit, and receives the incident light to generate a second localized plasmon resonance sensor signal. The carrier is used for placement of the reference optical fiber and the sensing optical fiber. A processing unit is allowed to perform referencing on the second localized plasmon resonance sensor signal based on the first localized plasmon resonance sensor signal.
