Abstract

The present research focuses on designing and modeling a novel bimetallic surface plasmon resonance (SPR) sensor for non-invasive detection of lung and liver diseases by analyzing the volatile organic compounds (VOCs) in the exhaled breath. The proposed SPR sensor is designed with NaF prism/Ag/Au/ Ge₂Sb₂Te₅/BP/Sensing medium layer-by-layer arrangements. The finite element method (FEM) integrated COMSOL Multiphysics software tool is used to model the sensor and analyze the angular reflectivity. The thickness of different layers and the number of layers are carefully optimized to achieve high performance. The cornerstone of this research is to study the shift in the resonance angle by infiltrating different concentrations of VOCs in the sensing medium. Simulation outcomes revealed that the bimetallic sensor with an amorphous phase of GST and 18 BP layers bestows maximum performance. It is perceived that the proposed gas sensor accomplished a noteworthy sensitivity of 150⁰/RIU and 163.63⁰/RIU for detecting lung and liver diseases, respectively, which proves its potential application in the biomedical industries.

利用相变材料和黑磷对表面等离子体共振（SPR）气体传感器进行建模，用于肺和肝脏疾病的无创诊断

本研究的重点是设计和建模一种新型双金属表面等离子体共振（SPR）传感器，通过分析呼出气体中的挥发性有机化合物（VOCs）来实现肺部和肝脏疾病的无创检测。SPR传感器采用NaF棱镜/Ag/Au/ Ge2Sb2Te5/BP/传感介质逐层排列。利用有限元法集成COMSOL Multiphysics软件工具对传感器进行建模和角反射率分析。不同层的厚度和层数经过精心优化，以实现高性能。本研究的基础是研究不同浓度VOCs在传感介质中渗透后共振角的位移。仿真结果表明，具有GST非晶相和18 BP层的双金属传感器具有最佳性能。该气体传感器检测肺部疾病和肝脏疾病的灵敏度分别达到1500/RIU和163.630/RIU，证明了其在生物医学领域的潜在应用前景。
