This paper analyzes the sensitivity of the Kretschmann surface plasmon resonance (SPR) sensor and proposes a configuration that includes graphene layers to enhance sensitivity and act as a bio-compatibility agent, which can be used for biochemical sensors.
The sensitivity of a Kretschmann surface plasmon resonance (SPR) sensor was analyzed. The Kretschmann setup had multiple layers, a BK7 prism, silver, barium titanate (BaTiO3), titanium dioxide (TiO2), and graphene. The BaTiO3 and TiO2 coatings were sandwiched between two silver layers. The sensitivity of 260(degrees)/RIU has been achieved. The graphene layers are added to the configuration to improve sensitivity and as a bio-compatibility agent. This configuration can be used for biochemical sensors.
