Abstract In recent decades, significant progress has been made in the development of quantum dots (QDs) as sensing materials in advanced sensor technology. This review discusses the brief history, significance, and advancements of QD-based gas sensors. Additionally, it emphasizes the integration of artificial intelligence (AI) and nanotechnology to enhance sensing performance. These advancements have resulted in improved selectivity, sensitivity, and overall performance. However, challenges such as reproducibility and environmental stability persist, requiring further investigation. Emerging innovations are actively addressing these limitations that aims for the wider implementation of QD-based gas sensors. Given their transformative potential, these materials could play a crucial role in industrial safety, medical diagnostics, and environmental monitoring.
