Among other carbon-based nanomaterials, graphene represents a great promise for gas sensing applications. In 2009 the detection of individual gas molecules of NO[sub]2[/sub] adsorbed onto graphene surface was reported for the first time. This initial observation has been successfully explored during the recent years. The Nanobioelectronics & Biosensors Group at Institut Català de Nanociència i Nanotecnologia (ICN2), led by ICREA Research Professor Arben Merkoçi, published in Small a work showing how to use a Graphene/Silicon Heterojunction Schottky Diode as a sensitive, selective and simple tool for vapors sensing. The work was developed in collaboration with researchers from the Amirkabir University of Technology (Tehran, Iran).
