“…So far, many optical glucose sensors have been developed based on SPR mechanism [1,2]. A glucose SPR sensor has been presented recently which is composed of nanolayers of silver, MXene, ZnO, and graphene over a BK7 prism and the highest sensitivity of 132.5 deg RIU −1 has been achieved [1]. A low-cost Ag-based SPR glucose biosensor has been reported with sensitivity and figure of merit of 288.86 deg RIU −1 and 88.89 RIU −1 , respectively with optimized graphene and WS 2 layers [2].…”

In this article, a highly efficient surface plasmon resonance sensor for glucose detection in urine biosamples is presented. The proposed structure with the Ag-Si-Ag configuration was investigated and optimized using the transfer matrix method. In addition, blueP/WS2 and ZnO layers were implemented to further improve the sensitivity of the sensor by light-mater interaction enhancement in the sensing layer. The multilayer configuration of the optimized sensor consists of SiO2 prism /ZnO /Ag1/ Si/Ag2 /ZnO /blueP/WS2 layers, respectively and operates at λ=633 nm. Different glucose concentrations of 0 to 15 mg/dl (for non-diabetic person), 0.625 gm/dL, 1.25 gm/dL, 2.5 gm/dL, 5 gm/dL, and 10 gm/dL (for diabetic body), with refractive indices of 1.335, 1.336, 1.337, 1.338, 1.341, and 1.347, respectively have been regarded and the qualification parameters of S=320 deg/RIU, FWHM=1.5767 deg, FOM=215.99 RIU-1, and minimum reflectance of 0.0318 have been evaluated. We believe that the proposed sensor could pave the way to easy and accurate detection of glucose concentration which is vital in control or treatment of diabetes.

“…It was shown that adding a graphene layer to the SPR sensor structure can improve the tuning range and sensitivity [19] as a protection layer to the plasmonic metal from oxidation and this can lead to more stability of the performance. Typically, two-dimensional/TMD heterostructures or Perovskite materials are employed in metal prism-based biosensors [20][21][22][23][24][25]. The twodimensional nanomaterial BaTiO 3 is a desirable option for thin-film electro-optic switches because it has substantial electro-optical coefficients [26].…”

Organic compound-based sensors are used in a variety of significant fields, including medical research, azeotropic calibration, vegetable oil extraction, the shoe industry and geothermal power plants. Here, a high-performance, two-dimensional material-based organic compound sensor has been proposed using a surface plasmon resonance (SPR) nanostructure consisting of a BK7 glass prism, Ag, BaTiO 3 , Ag, graphene and sensing layer. The reflectivity curves of the SPR device have been investigated when the sensing media are Pentane, n-Hexane, n-Heptane and n-Octane. The thickness of the BaTiO 3 layer and the number of graphene sheets have been optimized to maximize the sensitivity. The highest sensitivity attained is 220.83 deg/RIU for n-Octane with 45 nm silver/10 nm BaTiO 3 /8 nm silver and four layers of graphene. We believe that the SPR-based sensors are simple and can replace the spectrometry, chromatography and electrochemical based sensors. The proposed design is extremely effective for diverse applications in biological, industrial and chemical detection because of its simple structure and great performance.

This paper presents a performance comparison of heterostructure surface plasmon resonance (SPR) biosensors for the application of Novel Coronavirus SARS-CoV-2 diagnosis. The comparison is performed and compared with the existing literature based on the performance parameters in terms of several prisms such as BaF 2 , BK 7 , CaF 2 , CsF, SF 6 , and SiO 2 , several adhesion layers such as TiO 2 , Chromium, plasmonic metals such as Ag, Au, and two-dimensional (2D) transition metal dichalcogenides materials such as BP, Graphene, PtSe 2 MoS 2 , MoSe 2 , WS 2 , WSe 2 . To study the performance of the heterostructure SPR sensor, the transfer matrix method is applied, and to analyses, the electric field intensity near the graphene-sensing layer contact, the finite-difference time-domain approach is utilized. Numerical results show that the heterostructure comprised of CaF 2 /TiO 2 /Ag/BP/Graphene/Sensing-layer has the best sensitivity and detection accuracy. The proposed sensor has an angle shift sensitivity of 390°/refractive index unit (RIU). Furthermore, the sensor achieved a detection accuracy of 0.464, a quality factor of 92.86/RIU, a figure of merit of 87.95, and a combined sensitive factor of 85.28. Furthermore, varied concentrations (0–1000 nM) of biomolecule binding interactions between ligands and analytes have been observed for the prospects of diagnosis of the SARS-CoV-2 virus. Results demonstrate that the proposed sensor is well suited for real-time and label-free detection particularly SARS-CoV-2 virus detection.
