TL;DR: In this article, the numerical analysis of surface plasmon resonance biosensor based on graphene on aluminum and silicon has been performed and it has been shown that the application of monolayer or bilayer graphene over aluminum not only protects it from oxidation but also enhances the adsorption of biomolecules, which results in the detection of large refractive indices ranging from aqueous solution to biom molecules (refractive index 1.330 to 1.480).

TL;DR: In this article, the authors proposed a highly sensitive temperature sensor based on photonic crystal surface plasmon waveguides comprising different plasmoric active metals such as gold, silver, and aluminum.

TL;DR: In this paper, the authors numerically demonstrate and propose sensitivity enhancement of surface plasmon resonance (SPR)-based conventional gaseous sensor using few layers of black phosphorous (BP), as compared with other 2D material such as graphene and molybdenum disulphide (MoS2).

TL;DR: In this article, a surface plasmon resonance (SPR) based gas sensor in terahertz frequency with Otto configuration based on attenuated total reflection (ATR) technique using free standing doped graphene monolayer.

TL;DR: In this article, a SPR based gas sensor using doped graphene monolayer employing the ATR technique via modified Otto coupling configuration was reported, which is an approach different from the already reported Otto geometry for SP excitation in terahertz frequencies where the air gap has been replaced by a dielectric spacer layer (organic material) of refractive index 1.44, 1.50 and 1.54.
