The proposed refractive index-based biosensor made of cost-effective polymer material in Mach-Zehnder configuration with novel horizontal slot waveguide structure offers high sensitivity. Due to the recent demand for low-cost point-of-care biosensor, silicon wafer-based has potential developing new hybrid waveguides sensors. Hence we designed BenzoCycloButene (BCB), SU8 as core, and polymethyl methacrylate (PMMA) clad on a wafer. novelty BCB 2.5 μ m wide 1.8μ thick height 400 ​nm, which handles analyte effectively without any external sample holder. In Interferometer architecture, reference arm 1 ​cm sensing at length 1.1 index cancer cell (RI ​= ​1.401) Influenza A type virus ​1.48) are used. Effective mode core investigated through Finite-difference time domain (FDTD) analysis, sensitivity results calculated. Detection disease plotted transmission spectrum normal human serum ​1.35). This achieves 19280 nm/RIU provides 16500 nm/RIU, is higher this based biosensing.

The coronavirus (SARS-CoV-2) disease has affected the globe with 770 437 327 confirmed cases, including about 6 956 900 deaths, according to World Health Organization (WHO) as of September 2023. Hence, it is imperative develop diagnostic technologies, such a rapid cost-effective SARS-CoV-2 detection method. A typical biosensor enables biomolecule an appropriate transducer by generating measurable signal from sample. Graphene can be employed component for ultrasensitive and selective biosensors based on its physical, optical, electrochemical properties. Herein, we briefly review graphene-based electrochemical, field-effect transistor (FET), surface plasmon detecting target. In addition, details modification, immobilization, sensitivity limit (LOD) all three sensors regard were reported. Finally, point-of-care (POC) using portable smartphone wearable watch current topic interest.
