Abstract
The apparatus for making a nanopore in a membrane generally has an electrode configured to connect to one of two opposing surfaces of the membrane; a conductive tip configured to contact a location of the other one of the two opposing surfaces of the membrane; and a voltage source electrically connected between the electrode and the conductive tip and operable to generate an electric potential across the membrane, the electric potential locally removing material of the membrane at the location to make the nanopore.
