Nanostructured MoS₂-Based Advanced Biosensors: A Review

The introduction of nanotechnology in biosensor applications has significantly contributed to human lifestyle by rendering advanced personalized diagnostics and health care and monitoring equipment and techniques. Nanomaterials and nanostructures have recently gained impetus in the domain of biosensors because of their manifold applications. Transition-metal dichalcogenides (TMDs) newly attracted interest because of their multidimensional structures and structure-dependent unique electronic, electrocatalytic, and optical properties, which can be explored to design novel biosensing platforms. The content of the present article aspires to advocate a critical evaluation on the recent advances in the domain of dimensionally different MoS2, the most widely explored TMD, and their relevance in biosensing application. This encompasses the major structural attributes and synthetic methodologies of zero-, one-, two-, and three-dimensional MoS2 nanostructures, pertaining to their biosensing potential. Herein, we described the prevailing and potential applications of MoS2 nanostructures in optical, electrochemical, and electronic biosensors.
