Abstract

This manuscript aims to analyze the effect of bariumtitanate (BaTiO₃) and molybdenumdisulfide (MOS₂) along with gold (Au) on the sensing application of surface plasmon resonance (SPR) biosensors. The proposed multilayer structure has a BK7 prism, a bimetallic layer of Au, BaTiO₃, and a MOS² layer. BaTiO₃ and MOS₂ layers are used to improve the biosensor performance parameters by the Kretschmann configuration. The proposed configuration has enhanced the performance over the conventional sensor. The performance parameters like full width half maximum (FWHM), detection accuracy, and detection accuracy have been analyzed. The suggested biosensor can detect a wide range of analytes with an extensive refractive index range. The proposed sensor can be used to analyze chemical and biological analytes.
