NO\n                    <jats:sub>2<\/jats:sub>\n                    is one of the most toxic gases in daily life, which induces severe respiratory diseases. Thus, the real\u2010time monitoring of low concentrations of NO\n                    <jats:sub>2<\/jats:sub>\n                    is highly required. Herein, a visible light\u2010driven ultrasensitive and selective chemoresistive NO\n                    <jats:sub>2<\/jats:sub>\n                    sensor is presented based on sulfur\u2010doped SnO\n                    <jats:sub>2<\/jats:sub>\n                    nanoparticles. Sulfur\u2010doped SnO\n                    <jats:sub>2<\/jats:sub>\n                    nanoparticles are synthesized by incorporating\n                    <jats:sc>l<\/jats:sc>\n                    \u2010cysteine as a sulfur doping agent, which also increases the surface area. The cationic and anionic doping of sulfur induces the formation of intermediate states in the band gap, highly contributing to the substantial enhancement of gas sensing performance under visible light illumination. Extraordinary gas sensing performances such as the gas response of 418 to 5\u00a0ppm of NO\n                    <jats:sub>2<\/jats:sub>\n                    and a detection limit of 0.9 ppt are achieved under blue light illumination. Even under red light illumination, sulfur\u2010doped SnO\n                    <jats:sub>2<\/jats:sub>\n                    nanoparticles exhibit stable gas sensing. The endurance to humidity and long\u2010term stability of the sensor are outstanding, which amplify the capability as an indoor air quality monitoring sensor. Overall, this study suggests an innovative strategy for developing the next generation of electronic noses.\n
