Ultrasensitive gas sensor based on epitaxial graphene on SiC has been fabricated. The sensor exhibits strong and reproducible response to nitrogen dioxide (NO2) in the concentration in air down to 1 part-per billion (ppb). Prototype of the transportable device for environmental monitoring allows fast and reproducible measurements of NO2 concentration in the range typical for environmental pollution (5 ppb – 50 ppb).
