Two-dimensional (2D) nanomaterials have undergone a significant evolution from the initial isolation of graphene to the emergence of specialized families like MXenes, TMDs, and MBenes. These materials are characterized by their atomic-scale thickness, which provides a massive surface-to-volume ratio, high carrier mobility, and tunable electronic properties essential for advanced sensing and energy technologies. The focus of research has shifted from simple detection to high sensitivity biosensing and environmental monitoring through hybrid nanostructuration. MXenes & MBenes: These have become the most extensively utilized 2D materials beyond graphene for biosensing. MBenes (transition metal borides) are specifically noted for detecting ultra-low concentrations of hazardous toxic in food (e.g., Roxarsone, Theobromine, and Bisphenol A) with unprecedented speed and sensitivity. 

Disease Diagnostics: 2D materials like g-C₃N₄ and MoS₂ are being engineered as scaffolds for biomolecular assemblies to detect cancer biomarkers (e.g., miRNA, Tryptophan), glucose, and viruses with high accuracy. Environmental Protection: New graphene-modified electrodes enhanced with metal nanoparticles allow for the detection of heavy metals (mercury). Non-Enzymatic Sensing: To overcome the high cost and instability of enzymes, 2D sensing layers (like rGO, MXene, C₃N₄ with bimetal oxides and metal nitrides) are being used directly as electrocatalysts for redox reactions, simplifying device design for real-time monitoring.
