Designing of High-Sensitivity Optical Surface Plasmon Resonance Sensor (OSPRS) for Fast and Accurate Diagnosis of Dengue Virus (DeVs)

Dengue virus (DeVs) is one of the most widespread and dangerous viruses. Early discovery is crucial to help in treatment of the DeVs illness. Currently, the traditional approaches for detecting DeVs infection have a lot of limitations like length of time and complexity. As a result, the scientists and engineers work hard on designing steadfast, quick, simple, low-cost, and highly insightful systems to sense of DeVs. This work introduces an optical surface plasmon resonance sensor (OSPRS) for rapid diagnosis of DeVs. The hybrid configuration of OSPRS involves silver (Ag) and nickel (Ni) inserted between titanium dioxide (TiO₂) and black phosphorus (BkP) layers. The investigations of the OSPRS have been performed by Mathematica software with help of the transferee matrix approach (TMA). The thicknesses of OSPRS layers are inspected and studied to get the best efficiency. The uppermost sensitivity is reached as 299.42 deg∕RIU with 45 nm of Ag, 2 nm of TiO₂, 5 nm of Ni, and 4 sheets of BkP. Also, the OSPRS has unique strengths like fast response, simple structure, and tumble design. As a result, the advised OSPRS can be employed effectively for diagnosis of the infected blood components by DeVs.
