Innovative sensor specifically and precisely detects molecules

Researchers of Karlsruhe Institute of Technology (KIT) and Technical University of Darmstadt have developed a novel sensor for gas molecules by combining a graphene transistor with a customized metal-organic coating. The innovative sensor specifically and precisely detects molecules and represents the prototype of an entirely new class of sensors. The ethanol sensor developed responds to neither other alcohols nor humidity. The results are reported in Advanced Materials.
