Deskripsi
Field effect transistors based on graphene hold promise for sensing applications. Here, the authors report a millimeter-sized transistor based on deformed graphene as a biosensor that can detect nucleic acid molecules having detection limit of ~18 molecules of DNA in physiological buffer solution and ~600 molecules in human serum.
