Abstract
The present invention relates to a graphene transistor comprising: a substrate; a graphene channel layer arranged on the substrate; a pair of metals spaced from each other and respectively arranged at opposite ends of the graphene channel layer; and a linker layer arranged on the graphene channel layer and including an N-heterocyclic carbene compound, a fabrication method therefor, and a biosensor comprising the same. The graphene transistor according to the present invention in which the carbene group of the N-heterocyclic carbene compound forms a covalent bond with the graphene channel layer to modify the whole surface of the graphene channel layer exhibits excellent electric conductivity as a transistor and a biosensor comprising the transistor is improved in selectivity and sensitivity.
