The surface plasmon resonance-based fiber optic sensors: A theoretical comparative study with 2D TMDC materials

Surface plasmon resonance biosensors are drawing attention due to their real-time, label-free, and rapid characteristic. To detect trace biomarkers (ct-DNA, mi-RNA, PD-L1), plasmonic and metal oxide nanoparticles have been utilized for signal amplification and have shown exciting results. To achieve uniform, reproducible, simple, and sensitive sensor interface construction, two-dimensional materials such as graphene and molybdenum sulfide have opened a research upsurge and show a great possibility in the surface plasmon resonance biosensing field due to their unique large specific surface area, excellent in-plane electron transport effect, and singular optical properties. Here, we provide an overview of the recent research progress on two-dimensional materials in the field of surface plasmon resonance biosensors, including the optoelectronic properties of two-dimensional materials, sensitivity enhancement mechanism, and interface construction. Finally, the challenges and development directions of detection sensitivity enhancement are summarized and prospected. Our work will provide a useful platform to expand the further application of two-dimensional materials in surface plasmon resonance biosensors.

Two-dimensional (2D) materials are attracting attention because of their outstanding physical, chemical, and electrical properties for applications of various future devices such as back-end-of-line (BEOL) field effect transistor (FET). Among many 2D materials, tin disulfide (SnS2) is advantageous for low temperature processing due to a low melting point, which is a pre-requisite in the production of flexible and BEOL devices. However, this low temperature method produces poor crystallinity. Hence, many studies have aimed to improve crystallinity of SnS2 film for use in semiconductor industries. In this work, we propose a precursor multi-dosing method before deposition of SnS2. This precursor pre-treatment was conducted by atomic layer deposition (ALD) for improved adsorption of precursors to the substrate before general deposition. The film quality was analyzed by X-ray diffraction, Raman spectroscopy, transmission electron microscopy, atomic force microscopy, and X-ray photoelectron spectroscopy. These analyses showed a greater number of adsorbates after precursor pre-treatment, inducing a higher growth rate and better film crystallinity.

Resonance optical fiber sensors are widely studied for their high sensitivity, small size, and anti-electromagnetic interference. However, traditional resonance optical fiber sensors have encountered bottlenecks in the trace detection due to limited localized field intensity and low molecules affinity. With the development of materials technology, low-dimensional materials such as quantum dots, graphene, and transition metal sulfides have excellent properties such as high carrier mobility, large specific surface area, and flexible structure controllable artificial technologies that can also be used to synthesize new materials with desired characteristics, which can enhance the performance of sensors fundamentally. The introduction of low-dimensional materials can not only achieve the performance optimization of sensors, but also make sensors functional to realize the diversification of detection objects. This paper reviews the research progress of resonance optical fiber sensors based on low-dimensional materials. The detection principle and performance indexes related to resonance optical fiber sensing are elaborated, and resonance optical fiber sensors modified by low-dimensional materials are introduced. Furthermore, the role of low-dimensional materials in resonance fiber sensing is summarized, the direction of performance optimization in the production process of resonance fiber sensors is analyzed, and the future prospect of new resonance optical fiber sensors is given.
