Abstract

This paper studies a novel surface plasmon resonance (SPR) biosensor using a BK7 glass prism, a copper (Cu) metal plasmonic layer, which combine a halide perovskite (FASnI3) with two-dimensional (2D) materials such as phosphorus black, graphene and TMDC (MoS₂, MoSe₂, WS₂, WSe₂) for the detection of breast cancer cells. We have optimized the thickness of each layer in order to obtain maximum sensitivity. A numerical study mainly uses the transfer matrix principle, while the attenuation total reflection method involves examining the reflection properties. The evaluation of SPR biosensor configurations serves to obtain optimal performance. The simulation results indicate that the integration of halide perovskite (FASnI3) and 2D materials into the BK7/Cu/medium sensing structure significantly improves the sensitivity and figure of merit (ZT). The outstanding results in terms of sensor performance characteristics are observed in the BK7/Cu (48 nm)/FASnI3 (5 nm)/BP (0.53 nm) configuration. The figure of merit and sensitivity estimated at 123.11 RIU⁻¹ and 459.28°/RIU, with a notable improvement of 338.45 %.

在铜薄膜上使用卤化物过氧化物 FASnI3 和二维材料的超灵敏表面等离子体共振传感器

本文研究了一种新型表面等离子体共振（SPR）生物传感器，该传感器使用 BK7 玻璃棱镜、铜（Cu）金属等离子体层，将卤化物包晶（FASnI3）与磷黑、石墨烯和 TMDC（MoS2、MoSe2、WS2、WSe2）等二维（2D）材料相结合，用于检测乳腺癌细胞。我们优化了每一层的厚度，以获得最高灵敏度。数值研究主要使用传递矩阵原理，而衰减全反射方法则涉及反射特性的研究。对 SPR 生物传感器配置的评估有助于获得最佳性能。模拟结果表明，在 BK7/Cu/medium 传感结构中整合卤化物包晶（FASnI3）和二维材料可显著提高灵敏度和优点系数（ZT）。BK7/Cu (48 nm)/FASnI3 (5 nm)/BP (0.53 nm)配置在传感器性能特性方面取得了突出的成果。优点和灵敏度估计分别为 123.11 RIU-1 和 459.28°/RIU，显著提高了 338.45%。

期刊介绍： Results in Physics is an open access journal offering authors the opportunity to publish in all fundamental and interdisciplinary areas of physics, materials science, and applied physics. Papers of a theoretical, computational, and experimental nature are all welcome. Results in Physics accepts papers that are scientifically sound, technically correct and provide valuable new knowledge to the physics community. Topics such as three-dimensional flow and magnetohydrodynamics are not within the scope of Results in Physics. Results in Physics welcomes three types of papers: 1. Full research papers 2. Microarticles: very short papers, no longer than two pages. They may consist of a single, but well-described piece of information, such as: - Data and/or a plot plus a description - Description of a new method or instrumentation - Negative results - Concept or design study 3. Letters to the Editor: Letters discussing a recent article published in Results in Physics are welcome. These are objective, constructive, or educational critiques of papers published in Results in Physics. Accepted letters will be sent to the author of the original paper for a response. Each letter and response is published together. Letters should be received within 8 weeks of the article''s publication. They should not exceed 750 words of text and 10 references.
