Abstract: The present invention relates generally to the field of chemical sensing. More specifically, in certain aspects the present invention relates to graphene -based devices and methods useful in chemical sensing. One aspect of the invention is a sensing device including a first graphene grain; a second graphene grain disposed in substantial contact with the first graphene grain, the first graphene grain and the second graphene grain having a grain boundary formed therebetween; a first electrode operatively coupled to the first graphene grain; a second electrode operatively coupled to the second graphene grain; and an electrical measurement system coupled to the first electrode and the second electrode, the electrical measurement system being configured to measure one or more electrical properties of the grain boundary.
