“…In Eq. ( 16), we have selected the change in resonance angle spr with the shift angle spr and the change in refractive index unit (RIU) with n for each subsequent refractive index (n) increase with angular sensitivity measurement (S) [9].…”

“…However, when exposed to air or water, gold is significantly more resistant to oxidation than silver [8]. Because Ag metal is a good absorber, it creates a large number of surface plasmons (SP) at the metaldetection medium interface, resulting in a greater value of the resonance angle and a short peak of the reflectance curve with a considerable shift of the curve [9]. The surface plasmon resonance sensor's main features are discovered through graphical analysis and simulation using the MATLAB program.…”

“…The SPR sensor works on the basis of an optical phenomena in which a beam of p-polarized light meets particular resonance conditions, causing oscillations in charge density known as surface plasmon waves, SPW, to propagate along with the metal-dielectric interface. The state of plasmon resonance is described as [10]:…”

Recent scientific and technical advancements have resulted in the creation of very sensitive biosensing devices for pathogen detection. Surface plasmon resonance (SPR) has developed as an environmentally benign and effective label-free detection method in clinical research, notably for studying biomolecular interactions such as hemoglobin interactions. SPR can be used to assess blood abnormalities such as anemia, which is characterized by a transitory fall in blood hemoglobin concentration due to a decrease in red blood cell count. When compared to gold film sensors, using silver as the metal material and graphene to improves the sensitivity and gives a more distinct reflectance spectrum. The fundamental goal of this research is to improve hemoglobin detection sensitivity by concentration analysis, hence leading to a better knowledge of blood behavior utilizing SPR. This entails examining SPR reflectivity and calculating electromagnetic field dispersion in multilayer structures using a mechanism for wave propagation in stratified media based on transfer matrices.

A Kretschmann configuration‐based surface plasmon resonance sensor has been proposed. The sensor is made up of calcium fluoride prism, silver, silicon, and tungsten di selenide nanolayer. The theoretical and numerical study of SPR sensor have been analyzed by angle interrogation method with the help of MATLAB 2017b. The transfer matrix method (TMM) is the foundation for simulation and a monochromatic light of wavelength 633nm is considered as source. In the proposed device structure, each layer has been arranged in vertical format to improve the electrical and optical properties. The refractive index for analyte is considered as 1.330 to 1.335. Silver (Ag) metal is used for generation of surface plasmons. It has good chemical properties like metallic conductivity, chemical stability, band gap, small work function and acts as an adhesive layer between calcium fluoride prism and silicon layer. To improve the molecular contact and absorption, the transition metal dichalcogenide nanofilm tungsten di selenide (WSe2) is applied at the top. The sensitivity of 367.4 deg/RIU, detection accuracy of 0.4169 deg‐1, quality factor of 193.58, and full‐width half maximum of 1.8985 deg. are obtained optimized performance parameter of the proposed device structure.This article is protected by copyright.
