We propose a nucleobase-functionalized suspended graphene nanoribbon as an intrinsically selective device for nucleotide detection at ambient conditions. The proposed sensor combines Watson-Crick selective base pairing with graphene's capacity for converting anisotropic lattice strain to changes in an electrical current at the nanoscale.
