Graphene transistor containing functionalized N-heterocyclic carbene compound and its manufacturing method and biosensor including the same

摘要

The present invention relates to a substrate, a graphene channel layer arranged on the substrate, a pair of metals disposed apart at both ends of the graphene channel layer, and an N-heterocyclic carben arranged on the graphene channel layer. The present invention relates to a graphene transistor containing a linker layer made of a compound, a method for producing the graphene transistor, and a biosensor containing the graphene transistor. The graphene transistor according to the present invention exhibits excellent electrical conductivity as a transistor because the carbene group of the N-heterocyclic carbene compound and the graphene channel layer are covalently bonded to completely modify the surface of the graphene channel layer. However, the selectivity and sensitivity of biosensors including this are improved.
