Abstract
Ammonia (NH₃) is a corrosive gas that can pose significant risks to human health, even at low con-centrations. Its presence in exhaled breath can also serve as an indicator of various health conditions. This studydemonstrates that silicon nanowires (SiNWs) exhibit high sensitivity to NH₃, with notably improved performance inhumid environments. Incorporation of tungsten trioxide (WO₃) nanoparticles further enhances the sensor’s sensitiv-ity and accelerates its response time under a range of humidity conditions. These findings advance the developmentof robust, simple, and efficient NH₃ sensors, with potential applications in both environmental monitoring and medi-cal diagnostics.
