“…The layer of metal is used to generate the surface plasmons. The metal has poor adsorbability, so few layers of 2-dimensional material are associated with enhancing the biosensors’ performance [ 15 19 ]. When an incident light beam propagates through two media interfaces with the different refractive indexes at a particular angle and different dielectric constants, the surface plasmon gets excited [ 20 ].…”

“…The layer of metal is used to absorb the biomolecules or chemical molecules. The metal has poor adsorbability, so few layers of 2dimensional material is associated with enhancing the biosensors' performance [13]- [17]. When an incident light beam propagates through two media interfaces with the different refractive indexes at a particular angle and suitable dielectric constants (typically a metal with high concentration of free electrons and a dielectric medium), the Surface Plasmon gets excited [18].…”

“…Hence, the Kretschmann structure-based sensor is a promising method for sensing purposes. The sensitivity, detection accuracy, full width half maximum (FWHM), quality factor, etc., have been improvised using the modified multilayer Kretschmann structure [19]- [21].…”

“…The graphene layer improves the macromolecular captivation of the sensor. The BK7 prism is used as a coupling prism, the RI of the prism is given as [21]: (1) where λ is the wavelength of the applied optical signal. The RI of the metal layer (Ag) is expressed using the Drude model, = √1 − ( 2 )/[ 2 ( + )], where = 17.614μm and = 0.14541μm.…”
