    摘要: A light-assisted sensor and method of light-assisted sensing of gaseous species involves contacting a gaseous medium with a material selected to adsorb on its surface one or more gaseous species of interest and illuminating the surface of the material from a source to induce a change of an electrical property, such as conductivity, of the material in the presence of the one or more gaseous species. The change in the electrical property of the material is measured and can be used to identify and quantify the gaseous species of interest in the gaseous medium.
