Gas-Sensing Mechanisms of Water-Resistant Transition-Metal-Doped MoS ₂ for Lung Cancer Biomarker Detection

O, the doped systems can rapidly recover their structural integrity and electronic stability after water removal, demonstrating a strong anti-interference capability and environmental adaptability. This feature effectively suppresses the influence of nontarget species in complex breath environments and significantly improves the sensing reliability and reproducibility. From an application perspective, these findings provide valuable guidance for the design of high-performance gas sensors, offering key support for high-precision detection under complex conditions and representing an important step toward improving sensing accuracy and practical applicability.
