In this study, an angular interrogation technique has been used for modeling a highly sensitive surface plasmon resonance (SPR)based biosensor. The large surface area of the heterostructure of the blue phosphorene (BP/MoS 2 ) layer facilitates the biomolecules absorption. A four-layer Kretschmann model of the SPR biosensor containing the BP/MoS 2 heterostructure with a gold layer is proposed. Compared to the traditional gold fi lmbased SPR biosensors, the sensitivity of the proposed SPR biosensor has been signifi cantly improved. An enhanced sensitivity 224.57°/RIU has been achieved by optimizing the proposed structure with 50 nm thick gold layer and a monolayer of heterostructure BP/MoS 2 with a thickness of 0.75 nm. Moreover, the proposed BP/MoS 2 heterostructure off ers extremely small FWHM, high detection accuracy, and highquality factor parameters. The highest sensitivity of 252°/RIU was found with two-layers of BP/MoS 2 heterostructure confi guration. It is observed that, compared to previously reported sensitivity, the proposed SPR biosensor shows better results.
