Metalloporphyrin-SWCNT sensory arrays for discrimination of volatile organic compounds

May 13, 2015

Sophie's work with metalloporphyrin/single-walled carbon nanotube sensors has been published in Chemistry of Materials. Chemiresistors are made from pristine SWCNTs or SWCNTs mixed with tetraphenylporphyrin and metal complexes (Cr-Zn) thereof. Upon exposure to vapors of organic compounds, the resistances across an array of these materials give unique patterns that allow discrimination between amines, ketones, alcohols, aromatics, and aliphatics. Congrats Sophie!
