A gas sensor includes a sensing element including a substrate and a layer of carbon based nanostructures arranged on a surface of the substrate, wherein the carbon based nanostructures are arranged substantially perpendicular (e.g., at angles larger than 0 degrees) to the surface of the substrate, and wherein intercalation of a gas analyte between the carbon based nanostructures changes a conductivity of the layer of carbon-based nanostructures. The carbon-based nanostructures may include graphene nanoribbons (GNRs), laterally extended graphene nanoribbons (eGNRs), GNRs that comprise straight graphene nanoribbons, polycyclic aromatic hydrocarbons, or other graphene-based and graphene-related materials.
