- Abstract
There are numerous pharmacological uses for watery solution's sucrose concentration, including the preservation of food and proteins. It is imperative to create a sucrose detector that is quick, precise, and sensitive. In this communication, a surface plasmon resonance biosensor (SPRB) is employed for the determination of sucrose concentration. To achieve improved sensitivity, a Si layer is inserted between a metal (Ag) thin film and a black phosphor (BPS) layer in the proposed SPRB so that it has the design N-FK51A prism/silver/Si/BPS/ sensing medium (SM). Due to the exceptional dielectric properties of the Si layer, which include a high refraction index and low loss, it has been demonstrated that a little change in the analyte's refractive index can result in a substantial shift in the angle of resonance. By optimizing the thicknesses of the Ag, Si, and BP sheets, the suggested SPRB achieved an extraordinarily high sensitivity of 322.66°/RIU. Due to its great sensitivity, the suggested SPRB is enticing for usage in numerous biosensing applications.
