The designing of long-range surface plasmon resonance (LRSPR) biosensors using two-dimensional (2D) materials gained tremendous popularity due to their exclusive optoelectronic capabilities. Platinum diselenide (PtSe 2 ) is one of the members of this 2D family, having unique properties. An LRSPR biosensor with cytop/Ag/PtSe 2 configuration has been theoretically examined here. The transfer matrix method for TM mode was utilized in this study to compute the optical characteristics of the considered configurations for reflectance calculation. A new configuration of LRSPR biosensors based on BK7 prism/cytop/Ag/PtSe 2 has been presented to improve detection accuracy and quality factor. The proposed design of the LRSPR biosensor gives maximum detection accuracy and a quality factor of 100 ( ᵒ ) − 1 and 3400 ( R I U ) − 1 respectively with a sensitivity of 36.666 ᵒ /RIU. The proposed structure might be a biosensor for chemical detection, clinical diagnostics, and biological assessment.
