Abstract

A chemiresistive sensor has a low limit for detecting NOat ambient temperature. An active layer of the sensor includes a few-layer graphene material. The response of the sensor is not altered by relative humidity, and the sensor also demonstrates very low interference with ammonia, allowing this interference to be disregarded in the measurements.
