Nanopores are single nanometer-sized holes in thin insulating
membranes, which present a new tool for the detection and analysis of
individual biopolymers such as DNA. Applying a voltage bias, negatively
charged DNA molecules are pulled through the pore by the electric
field. When a molecule enters the channel, it displaces its own volume
of solution and hence it alters the pore ionic conductance. By
recording the ionic current it is possible to detect the passage of
individual molecules.
