PURPOSE: An apparatus and a method for ultrafast DNA sequencing using graphene nanoribbons are provided to quickly and accurately analyze the DNA sequence. CONSTITUTION: An apparatus for DNA sequencing using graphene nanoribbons comprises: a substrate with a nanogroove; the graphene nanoribbon placed on the substrate; electrodes for applying current, which are connected to both ends of the graphene nanoribbon; and an electrode for applying gate voltage. A method for sequencing using the apparatus comprises: a step of applying bias voltage between both electrodes of the graphene nanoribbons and applying alternating current gate voltage to a gate voltage; a step of towing DNA to be analyzed; a step of detecting current in real-time; and a step of analyzing relation between the current of the graphene nanoribbon and gate voltage. |
