Fig. 5: Detection of nicks in graphene nanopore FETs.

Ionic current and in-plane electronic current signals calculated for translocations of DNA strand with nicks between: a A–A, b C–C, c G–G, and d T–T through graphene nanopores. In all the cases, both current signals are averaged over time to show the variations clearly. The green tab in each plot indicates the time frame when the nick resides in the graphene nanopore.
