        abstract = {Nanomaterial-based gas sensors have emerged as a transformative technology in the detection of hazardous, combustible, and biologically relevant gases. The integration of nanomaterials into sensing platforms has significantly enhanced sensitivity, selectivity, response speed, and detection limits, even at trace concentrations. This paper presents a comprehensive and original review of nanomaterial-based gas sensors, emphasizing the functional role of nanomaterials, the fundamental mechanisms governing gas detection, and the major classes of nanostructured sensing materials. Furthermore, the paper discusses key application areas including environmental monitoring, industrial safety, healthcare diagnostics, and Internet of Things (IoT)-enabled smart sensing systems. Critical challenges related to selectivity, stability, and device integration are examined, followed by a discussion on future research directions focusing on hybrid nanomaterials, room-temperature operation, and intelligent sensing platforms.},
