This article proposes a biosensor based on surface plasmon resonance (SPR) for formalin detection, which achieves high sensitivity and can be used for detecting formalin of different concentrations.
Formalin detection is a deep concern in food items as its recurring consumption causes some life-taking diseases like chronic cancer. This article proposes a biosensor based on surface plasmon resonance (SPR) that uses this resonance-based concept for formalin detection. Our proposed hybrid design consists of two metallic layers of gold (Au), black phosphorus (BP) as a basic recognition element (BRE), and a single titanium dioxide layer (TiO2) film. The performance parameters were being calculated. The highest sensitivity achieved is 327.6deg/RIU for Bi-films of TiO2 and one BP film. By using attenuated total reflection (ATR), the formalin detection using biosensor with the help of reflectance and incident angle plot for various formalin concentrations. Finally, the previous and this comparative research analysis is being studied. The analysis of the proposed sensor has been carried out using COMSOL Multiphysics.
