||As air pollution from industrial and automobile emission becomes more and more severe, the
personalized, integrated gas sensor is desirable for everyone to monitor everyday's air quality as well
as their personal health condition non-invasively. Such sensor should have the desirable features
like energy efficient, miniature size, accurate response (down to ppm level), and selectivity.
Traditional bulk MOX based gas sensor works in the temperature range of 300 to 400 oC, which
requires large amount of energy to power the heater. We here propose using graphene based field
effect transistor as label-free sensor platform, to detect gas selectively by measuring its
electrical properties at room temperature.
