摘要
Two-dimensional (2D) nanomaterials such as graphene, transition metal dichalcogenides, black phosphorus, metal-organic framework, MXenes, and metal oxide nanosheets, etc. are being envisioned as the next-generation sensing materials for extremely diversified sensing applications and nano-electronics owing to their excellent electrical, mechanical, physicochemical and optical properties. These 2D nanomaterials-based semiconductor gas sensors have unlocked a new horizon in the field of non-invasive detection of diseases, through the identification of the biomarkers in human breath. This review paper focuses on the different attributes of 2D nanomaterials, their sensing mechanism, and various methods utilized in the selective detection of biomarker molecules. Functionalization of 2D nanomaterials to fabricate semiconductor-based gas sensors to distinguish between a healthy patient and a patient with the disease are discussed. Wherever relevant, limitations of the contemporary methods and future outlook have also been delineated.
