Surface plasmon resonance (SPR) biosensors based on transition metal dichalcogenides (TMDC) materials have shown improved performance in terms of sensitivity, detection accuracy (DA), and quality factor (QF) over conventional biosensors. In this paper, we propose a five-layers model containing black phosphorus (BP) and TMDC (Ag/BP/WS2) in Kretschmann configuration. Using TM-polarized light at 633 nm, we numerically demonstrate the highest sensitivity (375°/RIU), DA (0.9210), and QF (65.78 1/RIU) reported so far over similar materials. Refractive index (RI) of the coupling prism has also played an essential role in enhancing the performance of these biosensors. The research on TMDC materials is still new, and these materials bring about opportunities to develop a new class of biosensor.

“…The evanescent wave excites surface plasmon wave (SPW) at the metal-dielectric interface when the wave vector of the evanescent wave is matched with the surface plasmon wave [k ev. = Real{k spw }] [5]. The spatial extension of surface plasmons (SPs) in the sensing medium is characterized by two parameters: (1) field penetration depth in the transverse direction and (2) propagation length of SPs in the lateral direction.…”

This work presents a surface plasmon resonance biosensor for the figure of merit enhancement by using Ga-doped zinc oxide (GZO), i.e., nanostructured transparent conducting oxide as plasmonic material in place of metal at the telecommunication wavelength. Two-dimentional graphene is used here as a biorecognition element (BRE) layer for stable and robust adsorption of biomolecules. This is possible due to stronger van der Waals forces between graphene's hexagonal cells and carbon-like ring arrangement present in biomolecules. The proposed sensor shows improved biosensing due to fascinating electronic, optical, physical, and chemical properties of graphene. This work analyses the sensitivity, detection accuracy, and figure of merit for the GZO/graphene SPR sensor on using the dielectric layer in between the prism and GZO. The highest figure of merit of 366.7 RIU − 1 is achieved for the proposed SPR biosensor on using the nanostructured GZO at the 3000 nm dielectric thickness. The proposed SPR biosensor can be used practically for sensing of larger size biomolecules with due availability of advanced techniques for the fabrication of the nanostructured GZO and graphene.

“…Wu et al [11] remarkably enhanced the sensitivity of SPR biochemical sensor by using heterostructure of few-layer BPgraphene/TMDC materials. Pal et al [12] improved the sensitivity of SPR biosensor 1.42 times of conventional and 1.40 times of graphene-based SPR biosensor by using BP. To further enhance the sensitivity and FWHM of the SPR biosensor by utilising the light absorption properties of BP, here, we use a heterostructure of Si nanosheet with monolayer BP onto a gold surface.…”
