2D Nanomaterial-Based Surface Plasmon Resonance Sensors for Biosensing Applications

Abstract

The absorption and binding energy of material plays an important role with a large surface area and conductivity for the development of any sensing device. The newly grown 2D nanomaterials like black phosphorus transition metal dichalcogenides (TMDCs) or graphene have excellent properties for sensing devices’ fabrication. This paper summarizes the progress in the area of the 2D nanomaterial-based surface plasmon resonance (SPR) sensor during last decade. The paper also focuses on the structure of Kretschmann configuration, the sensing principle of SPR, its characteristic parameters, application in various fields, and some important recent works related to SPR sensors have also been discussed, based on the present and future scope of this field. The present paper provides a platform for researchers to work in the field of 2D nanomaterial-based SPR sensors.

A Multi-Objective Optimization of 2D Materials Modified Surface Plasmon Resonance (SPR) Based Sensors: An NSGA II Approach

“…where C 1 has a value of 5.446 µm −1 . The optical parameters and the thickness of one monolayer of TMDC are 5.0805 + 1.1724i and 0.65 nm for MoS 2 [24], and 4.8937 + 0.3123i and 0.8 nm for WS 2 [24], respectively.…”

“…Various biosensors and immunosensors with a great performance based on these 2D materials have been proposed such as: dopamine, ascorbic acid and uric acid detection sensors [21]; single strand DNA (ssDNA) interaction sensors [22]; and sensors used in the detection of prostate-specific antigens [23]. Furthermore, the main drawback of graphene coated sensors is that the increased overall absorption with the number of monolayers added, could be overcome by using these new materials as they show a high absorption for only one monolayer [24][25][26].…”

Emerging Biosensors for Oral Cancer Detection and Diagnosis—A Review Unravelling Their Role in Past and Present Advancements in the Field of Early Diagnosis

“…Advancements in nanotechnology offer the necessary impetus for the development of nanobiosensor technologies [ 93 , 94 ]. Individual/singular optimisation is required for characteristics such as specificity, sensitivity, shelf life, linearity, detection limit, reaction time, and repeatability, which influence the performance of a nanobiosensor [ 95 ].…”

Infrared Polaritonic Biosensors Based on Two-Dimensional Materials

“…Many reports have introduced the employment of only graphene or metal to excite SPPs to strengthen the mid-IR based biomolecular fingerprint [ 72 ]. There is a limitation in measuring the binding of low molecular weight analysts in the mid-IR range.…”
