Abstract

The development of next-generation sensing technologies heavily depends on the synthesis, design, and physical characteristics of sophisticated nanomaterials. Superior sensitivity, selectivity, and response kinetics are made possible by materials' improved surface-to-volume ratios, quantum confinement effects, and programmable electronic structures at the nanoscale. Hydrothermal, sol-gel, and self-assembly techniques are examples of recent synthetic developments that enable exact control over composition and morphology, making optimization for particular sensing functions easier. While two-dimensional MXenes offer superior conductivity and surface functionality for electrochemical detection, one-dimensional SiC nanostructures offer great heat stability and electron mobility. Carbon-based nanomaterials are perfect for biosensors because they exhibit effective charge transfer and biocompatibility. By adjusting defect density [1], doping techniques, such as holmium in NiO, improve gas sensing. Self-powered, flexible sensors that transform mechanical inputs into electrical signals without the need for external power sources are made possible by the integration of piezoelectric and triboelectric nanogenerators [2-4]. This review synthesizes recent progress in nanomaterial design, examines structure-property relationships critical to sensor performance, and evaluates applications across chemiresistive, optical, and electrochemical platforms, highlighting pathways toward real-world deployment in healthcare, environmental monitoring, and wearable electronics.
