“…A 65 nm thick silicon layer separates graphene and gold layers. By adding a WS 2 layer, the sensitivity of the designed sensor is increased to 333.33 • /RIU, surpassing that in references [12,[16][17][18][19][20]. The value of the FWHM is approximately 2.81 • , making it applicable in sensor-based setups.…”

“…For example, Moradiani et al presented a structure using polysilicon, silicon, gold, and graphene at terahertz wavelengths, achieving sensitivity of 45.14 • /RIU [16]. Menon et al employed graphene and MoS 2 , along with a prism and a gold metal layer, at a wavelength of 633 nm [17]. Their biosensor demonstrated sensitivity of 130 • /RIU, indicating that the addition of a graphene layer to the metal layer enhances the sensitivity.…”

In this study, a Kretschmann structure with a hybrid layer of graphene–WS2 is designed to develop a sensitive biosensor for deoxyribonucleic acid detection. The biosensor incorporates a 45 nm gold layer as the active layer and a thin film of chrome as the adhesive layer. Through the optimization of the graphene and WS2 layers, combined with the implementation of a silicon layer, we can enhance the nano-sensor’s sensitivity. The thin silicon layer acts as a protective barrier for the metal, while also increasing the volume of interaction. Consequently, by adjusting the thickness of the active metal and adding a silicon layer, we achieve higher sensitivity and a lower full width at half maximum, leading to sensitivity of 333.33°/RIU. The designed structure is analyzed using numerical techniques and the finite difference time domain method, allowing us to obtain the optical characteristics of the surface plasmon polariton sensor. Various parameters are calculated and evaluated to determine the optimal conditions for the sensor. Furthermore, the total size of the sensor is 2.228 µm2.

“…In general, SPR has been used to detect a variety of targets, including glucose [ 40 – 42 ], uric acid [ 43 , 44 ], dopamine [ 27 , 45 , 46 ], antibody [ 47 – 50 ], antigen [ 47 , 51 , 52 ], salmonella [ 53 ], urea [ 43 , 54 – 56 ], and creatinine [ 28 , 57 , 58 ], in a variety of applications, including material characterization, medical diagnostics, food quality sensors, and drug development. Yu et al described the development of a D-shaped fiber SPR glucose biosensor with a modified MoS2-graphene composite nanostructure that exhibits approximately fourfold increased sensitivity [ 40 ].…”

SPR-based technology has emerged as one of the most versatile optical tools for analyzing the binding mechanism of molecular interaction due to its inherent advantages in sensing applications, such as real-time, label-free, and high sensitivity characteristics. SPR is widely used in various fields, including healthcare, environmental management, and food-borne illness analysis. Meanwhile, kidney disease has grown to be one of the world’s most serious public health problems in recent decades, resulting in physical degeneration and even death. As a result, several studies have published their findings regarding developing of reliable sensor technology based on the SPR phenomenon. However, an integrated and comprehensive discussion regarding the application of SPR-based sensors for detecting of kidney disease has not yet been found. Therefore, this review will discuss the recent advancements in the development of SPR-based sensors for monitoring kidney-related diseases. Numerous SPR configurations will be discussed, including Kretschmann, Otto, optical fiber-based SPR, and LSPR, which are all used to detect analytes associated with kidney disease, including urea, creatinine, glucose, uric acid, and dopamine. This review aims to show the broad application of SPR sensors which encouraged the development of SPR sensors for kidney problems monitoring.

“…As the wave vector of air and light matches by controlling thin film thickness and light incident angle, the resonance will be achieved resulting the excitation of surface plasmon polaritons (SPP) [16,17]. In short, SPR can be produced by using two techniques, namely prism coupling technique [18] and fiber based technique [19]. The main requirement to generate SPR is the presence of noble metal such as gold and silver.…”

Two types of fiber optics, namely macro etched silica single mode fiber (SMF) and Fiber Bragg Grating (FBG) (Bragg wavelength of 1550 nm and 1554 nm) had been used to detect various types of honey samples, such as Apis Dorsata Honey, Trigona Honey and Capilano Australian Honey. To study the effect of exposure period in open environment at room temperature, all honey samples were exposed in open environment at room temperature from 2 to 10 days. In comparison with macro etched SMF and FBG (λB=1554 nm), the FBG (λB=1550 nm) portrays an excellent sensing properties with sensitivity and selectivity of 33.56 dB/RIU and 24.07 dB/RIU respectively. The output of this work concludes that the quality of honey based on optical output power reduces up to 0.35% as period of exposure to the open environment increased.
