To resolve this issue, an intriguing approach has been recently proposed, namely, to use nanopores drilled in monoatomic layer graphene. The one-atom-thick nature of graphene could provide the highest spatial resolution as it forms only one recognition point for identifying nucleotides. It has been predicted theoretically that a graphene nanogap or nanopore could read DNA by measuring the nucleobase’s transverse conduction. Indeed, the translocations of DNA molecules through nanopores in monolayer and multilayer graphene have been realized experimentally and computationally, still by monitoring ion current blockage. However, signals at a resolution suitable for distinguishing between nucleotides have not been yet achieved in these studies on graphene nanopores with diameters down to
