研究目的
To present a three-core photonic crystal fiber (PCF) surface plasmon resonance (SPR) biosensor with high performance, easy implementation, and good repetition for real-time detection of bio-molecules and small drug-molecules.
研究成果
The proposed three-core PCF-SPR biosensor has a higher sensitivity and larger detection range, with an average refractive index sensitivity of 3435 nm/RIU and a resolution of 2.91 × 10?6 RIU. It is easier to implement at the present level of technology and provides new ideas for the research of optical devices.
研究不足
The manufacture of designs that infiltrate the analyte in the inner air holes is very challenging, leading to the preference for externally coated metallic film SPR sensors.
1：Experimental Design and Method Selection:
The Full vector finite element method is used for numerical simulation and analysis of the transmission mode and characteristics of the three-core PCF-SPR biosensor.
2：Sample Selection and Data Sources:
The analyte is placed on the surface of the gold film.
3：List of Experimental Equipment and Materials:
The sensor uses a gold film as the outer layer and pure silica as the substrate material.
4：Experimental Procedures and Operational Workflow:
The structure parameters are optimized, and the influence of each parameter on the sensing performance is investigated.
5：Data Analysis Methods:
The sensing characteristics are described by wavelength interrogation method.
