Optical fiber surface plasmon resonance (SPR) sensors have advantages in chemical and biological sensing. The sensitivity of the sensor is mainly affected by the structure of the optical fiber sensor and the functional material. This paper introduces the structural design of optical fiber sensors and the classification of optical fiber sensitive materials. It also summarizes the latest applications of optical fiber SPR sensors in biochemistry and discusses the possible direction of future sensor development.
Optical fiber surface plasmon resonance (SPR) sensors have proven their particular advantages in chemical and biological sensing over conventional detection methods. By analyzing the principle of biochemical optical fiber SPR sensor, it is concluded that the main reason affecting the sensitivity of the sensor is the structure of the optical fiber sensor and the functional material. This paper briefly introduces the structural design of optical fiber sensors and focuses on the classification of optical fiber sensitive materials according to the principle of enhancing SPR effect. The latest applications of optical fiber SPR sensors in biochemistry in recent years are classified and summarized. The potential and obstacles in the current research are compared and analyzed. Finally, the possible direction of the sensor in the future is discussed.
