method and apparatus for fabricating a nanopore at a particular location on a membrane and method for increasing size of a nanopore on a membrane

摘要

One method for fabricating a nanopore at a particular location on a membrane includes controlling a dielectric strength of the membrane at a particular location on the membrane while applying one of an electrical potential or an electrical current to the membrane, monitoring an electrical property across the membrane while a among electrical potential or electrical current being applied across the membrane, detecting an abrupt change in electrical property across the membrane while one among electrical potential or electrical current is being applied across the membrane; and removing the electrical potential or electrical current from the membrane in response to detecting abrupt change in electrical property.
