... An attractive strategy for single-molecule DNA sequencing is to pass single-stranded DNA through a nanopore in a graphene monolayer. Here, the rings of carbon atoms in the graphene are depicted as hexagons, and the diameter of the nanopore is about 1.5 nm, corresponding to about 35 hexagonal units. ...
