A Review Functionalization and Hybridization of Two-Dimensional Transition Metal Dichalcogenides for Biosensing Applications

Two-dimensional (2D) transition metal dichalcogenides (TMDCs) have gained significant attention for extraordinary materials properties, which can lead to their enormous potential for biosensing applications. In particular, the richness of electronic and chemical properties of 2D TMDCs, and thereby biosensing performances can be tailored by functionalization and hybridization with extrinsic materials, including substitutional doping, metal nanoparticle functionalization, and formation of 2D heterostructures. Herein, we review the functionalization and hybridization of 2D TMDCs for biosensing applications. Through this, we aim to highlight the advantages of these approaches in modulating the intrinsic properties of 2D TMDCs, make them promising materials for next-generation biosensors.
