“…Considering the anisotropic nature of black phosphorous, Pal et al proposed a SPR sensor with Ag/BP/TMDS/Ti 3 C 2 T x vdW heterostructures [204]. Yet another SPR sensor based on BlueP/MoS 2 and Ti 3 C 2 T x with Ag metal layer was also proposed, replacing BP with Blue phosphorous (BlueP) [205]. Integration of 2D materials with plasmonic metal changes the flow of charge carriers towards the interface, hence enhances the electromagnetic field of SPPs at the interface.…”

Last decade has seen an explosion in the exploration of two-dimensional materials for optoelectronic applications owing to their novel optical and electronic properties. However, these materials, in general, are poor light absorbers with restricted spectral responsivity which limits their efficiency. Integration of these two-dimensional materials with each other and with plasmonic metal nanostructures enhances their light absorption efficiency and also influence the electronic properties. This review highlights the optical and electronic properties of two-dimensional materials integrated with other plasmonic two- dimensional materials or with plasmonic metal nanostructures. In addition, an overview of the optoelectronic properties of plasmonic nanostructure integrated two-dimensional heterostructures is also presented.

In this simulation work, comparative study of surface plasmon resonance (SPR) based sensor designed with gold (Au), Aluminium (Al), Silver (Ag) are numerically investigated to improve the performance parameter of device using Ni-Antimonene layer in the visible range of light at wavelength of 633nm. In this device configuration, different metals (Ag/Au/Al), a diamagnetic material (Fe2O3), Nickel (Ni) and 2D material Antimonene (Sb) is used with CaF2 glass prism using Kretschmann configuration with angle interrogation method. The angle interrogation method is used to examine the performance of the device. The performance parameters of SPR sensor such as sensitivity, detection accuracy (DA), quality factor (QF) has been calculated. The thickness of metals (Au/Al/Ag) and number of different material thickness has been optimized by using genetic algorithms to improve the performance of device. The present study reveals that Ag metal based SPR Sensor exhibit a higher sensitivity as compared to Al and Au based SPR sensor at 55 nm of thickness. At 55nm thickness of Ag minimum reflectance curve has been obtained in comparison with Au and Al. The studied multilayer configuration of SPR sensor device using different metal Au/Al/Ag with Fe2O3, Ni and Antimonene in presence of glass prism, the maximum sensitivity 3100/RIU is obtained in case of Ag. The sensitivities of Au and Al metals are 660RIU-1, 2040RIU-1 respectively which is less in comparison to Ag metal. The different performance parameter of SPR sensor such as sensitivity, full width at half maximum (FWHM) value, DA, figure of merit (FoM), limit of detection (LoD) is calculated for all three metals but in the case of Ag performance is good compared to Au and Al. The penetration depth (PD) 110.5nm and 3D plot of transverse electric (TM) field intensity have also been plotted. The proposed SPR sensor using Ag metal with highest sensitivity value has capability to detect the different liquid analytes in the field of biosensing application with large uses in biomedical field in visible range.

“…Ti 3 C 2 T x , WS 2 , and black phosphorus were theoretically presented in an SPR biosensor structure by Srivastava et al [ 26 ] with a monolayer of each nanomaterial and a sensitivity of 190.22 deg./RIU was achieved. S. Pal et al [ 27 ] recently presented an SPR biosensor based on a heterostructure of 2D BlueP/MoS 2 and Ti 3 C 2 T x for sensitivity improvement. For the proposed design using a CaF 2 prism, the researchers achieved a maximum sensitivity of 203 deg./RIU.…”

MXene (Ti3C2Tx) has emerged very recently as an interacting material for surface plasmon resonance (SPR) configuration. It was discovered that Ti3C2Tx can facilitate the adsorption of biomolecules due to its higher binding energies, stronger interaction between matter and light, and larger surface area. In this work, a two-dimensional Ti3C2Tx and silicon layer-based SPR refractometric sensor is proposed for the sensitive and fast detection of milk fat concentration due to the high significance of this issue to people all over the world. The proposed SPR structure employs BK7 (BK7 is a designation for the most common Borosilicate Crown glass used for a variety of applications in the visible range) as a coupling prism and silver as a metal layer. The layer thicknesses and the number of Ti3C2Tx sheets are optimized for the highest performance. The highest reached sensitivity is 350 deg./RIU with 50 nm silver and 4 nm silicon with a monolayer of Ti3C2Tx, which is ultra-high sensitivity compared to the latest work that utilizes SPR configuration. The proposed SPR-based sensor’s ultra-high sensitivity makes it more attractive for usage in a variety of biosensing applications.
