Abstract

Abstract A new gold film-molybdenum disulfide (MoS2)-hexagonal boron nitride (h-BN) three-layer sensing structure is reported for sensing applications. The strong photoelectric conversion of MoS2 and the wide forbidden band of h-BN are used to enhance the surface plasmon resonance of the gold film which greatly enhance the sensitivity of the sensor. The Au film was deposited on the optical fiber by controlled vacuum sputtering to monitor the thickness. The MoS2 nanolayer was deposited on the surface of the gold film by electrostatic adsorption and the hexagonal boron nitride nanolayer was subsequently superimposed to complete the preparation. The sensitivity of the prepared sensor was increased to 3803.0 nm/RIU, which is 71.5% higher than for the common gold film sensor. These results confirmed that this approach significantly upgraded the sensor performance. The newly proposed SPR sensor performed well using a simple structure, is low-cost, offers high accuracy and favorable specificity, and may be used for small molecule detection for medical applications.

基于金膜六方氮化硼-二硫化钼结构的光纤表面等离子体共振（SPR）传感器的灵敏度增强

摘要报道了一种用于传感应用的新型金膜二硫化钼（MoS2）-六方氮化硼（h-BN）三层传感结构。MoS2的强光电转换和h-BN的宽禁带被用来增强金膜的表面等离子体共振，这大大提高了传感器的灵敏度。通过控制真空溅射在光纤上沉积Au膜以监测厚度。通过静电吸附将MoS2纳米层沉积在金膜的表面上，随后将六方氮化硼纳米层叠加以完成制备。制备的传感器的灵敏度提高到3803.0 其比普通金膜传感器高71.5%。这些结果证实，这种方法显著提高了传感器的性能。新提出的SPR传感器使用简单的结构表现良好，成本低，具有高精度和良好的特异性，可用于医疗应用的小分子检测。

期刊介绍： Instrumentation Science & Technology is an internationally acclaimed forum for fast publication of critical, peer reviewed manuscripts dealing with innovative instrument design and applications in chemistry, physics biotechnology and environmental science. Particular attention is given to state-of-the-art developments and their rapid communication to the scientific community. Emphasis is on modern instrumental concepts, though not exclusively, including detectors, sensors, data acquisition and processing, instrument control, chromatography, electrochemistry, spectroscopy of all types, electrophoresis, radiometry, relaxation methods, thermal analysis, physical property measurements, surface physics, membrane technology, microcomputer design, chip-based processes, and more. Readership includes everyone who uses instrumental techniques to conduct their research and development. They are chemists (organic, inorganic, physical, analytical, nuclear, quality control) biochemists, biotechnologists, engineers, and physicists in all of the instrumental disciplines mentioned above, in both the laboratory and chemical production environments. The journal is an important resource of instrument design and applications data.
