Previous approaches relied upon detecting electrical changes in the graphene nanopore as the strand passed through; this new approach cleverly uses graphene nanoribbons with copies of nucleotide bases attached which chemically micro-bond to their respective opposite base (A<->T, G<-C) as the strand is passed through. This significantly improves accuracy of the detection method.
