Abstract
There is provided a substantially bare, self-supported single-layer graphene membrane including a nanopore extending through a thickness of the graphene membrane from a first to a second membrane surface opposite the first graphene membrane surface. A connection from the first graphene membrane surface to a first reservoir provides, at the first graphene membrane surface, a species in an ionic solution to the nanopore, and a connection from the second graphene membrane surface to a second reservoir is provided to collect the species and ionic solution after translocation of the species and ionic solution through the nanopore from the first graphene membrane surface to the second graphene membrane surface. An electrical circuit is connected on opposite sides of the nanopore to measure flow of ionic current through the nanopore in the graphene membrane.
