Nanopore-Based DNA Analysis via Graphene Electrodes

Figure 1

Principal diagram of nanopore-based DNA analysis: ssDNA is driven through a nanopore with two graphene electrodes by a longitudinal electric field; the transverse graphene electrodes are applied on defined voltage and used to measure the transverse current. The graphene electrodes are 8.6 Å wide and 12.1 Å apart. The SiN membrane and insulating cover layer are hidden in the graph.
