N2 - This paper presents an in silico study on the use of graphene and molybdenum disulfide to increase sensor sensitivity. A multilayer structure in the Kretschmann configuration whose optically coupled substrate is a polymeric trapezoidal prism is used in angular interrogation mode to detect changes in the order of 0.002 in the analyte layer. The graphene monolayers deposition above the metallic film results in a significant increase in the sensitivity, reaching 8452.11 nm/RIU. However, despite being widely used to improve sensor responsiveness in some SPR sensor models, the addition of the molybdenum disulfide layer reduces the improvement resulting from the insertion of the graphene layers.
