“…The prism-based kretschmann configuration have been widely investigated in recent years which facilitates the implementation of 2D materials and ligands, beside optimizing different layers' thickness and material type due to its layered structure to tailor field enhancement which could result in high sensitivity, accurate detection, and ease of binding of target molecules. The operation of kretschmann SPR sensor could be classified in to two categories of wavelength and angle interrogation in which the resonance is achieved by a dip in reflectivity versus wavelength spectra and incidence angle, respectively [19,20]. The metal attached to the prism plays an important role in characteristics optimization of SPR sensors.…”

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.

Nowadays there is an increasing request to realize green, eco-friendly and biodegradable electronic devices for biosensor implementation. In this context, we have conceived and realized a green sensor based on Localized Surface Plasmon Resonance (LSPR) phenomenon in a thin slab waveguide of Bacterial Cellulose (BC). These LSPR sensors can be obtained simply by gold sputtering on the slab BC waveguides. The performances have been studied investigating the presence of ionic liquids (ILs) inside and in absence of ILs with various thickness of the BC substrate. Depending of the thickness of the BC layer, the ILs effect on the LSPR can be constructive or destructive. In this work, we present a study of the sensor performances, in terms of bulk sensitivity and resolution by changing the aforementioned parameters. Analyses in terms of BC geometry are pursued in order to improve the interaction between the light and the LSPR phenomenon. The experimental setup used for this kind of extrinsic optical fiber LSPR sensor is based on two optical fibers used to connect a white light source and a spectrometer with the green LSPR sensor chip. Results evince the suitability of the proposed approach in order to realize sensors and biosensors with several intriguing properties and features. In fact, these LSPR platforms could be used to realize disposable biosensors, when a specific bioreceptor is covalently bonded to the gold.

“…Because of the poor absorbability of the noble metals, researchers are motivated to discover new materials to enhance the performance of the optical fiber-based biosensors. In recent time, numerous techniques and coating materials have been anticipated to improve the FOM and performance of the fiber optic SPR sensors (Tabassum and Gupta 2016;Mishra et al 2015;Rahman et al 2019a;Melo et al 2018Melo et al , 2019Nasirfar et al 2020;Xiong et al 2018;Ynag et al 2018;Mao et al 2015;Hu et al 2020). Bimetallic configuration of noble metals over step index multimode optical fiber, was demonstrated to enhance the FOM of a SPR sensor (Tabassum and Gupta 2016).…”

“…Highest value of FOM was achieved as 61.25 RIU −1 for the structure of sensor having 10-layers of black phosphorene coated over gold (Au). Additionally, the FOM was enhanced upto 75.523 RIU −1 by using 16-layers of graphene deposited over Ag-coated fiber core (Melo et al 2018). In 2019, Melo et al theoretically analyzed a SPR-based optical fiber tip sensor by employing graphene layers over a thin Au metallic nanofilm (Melo et al 2019) and 5-layers of graphene gives rise to optimum FOM value of 110 RIU −1 .…”

Topological insulators having topologically protected metallic surface state emerged out as new building blocks in electronics and photonics. In this paper, a high figure of merit (FOM) fiber optic surface plasmon resonance (SPR) sensor employing topological insulator, Bi 1.5 Sb 0.5 Te 1.8 Se 1.2 , is proposed theoretically. The designed SPR sensor utilizes wavelength interrogation-based Kretschmann-Raether configuration to evaluate the transmitted power using transfer matrix method. Maximum FOM achieved was 360.16 RIU −1 for the fiber configuration having 20-layers of Bi 1.5 Sb 0.5 Te 1.8 Se 1.2 coated over thin silver film. The performance of the sensor is also evaluated in terms of sensitivity and detection accuracy values. Authors believe that the derived results with enhanced performance can significantly boost the potential applications of topological insulators and hence BSTS material can find propitious chemical and biological sensing applications in future.
