1. A system for forming a nanopore, the system comprising:
a layer of transition metal dichalcogenide crystals;
an insulating material in contact with the layer of transition metal dichalcogenide crystals;
a first liquid disposed on a first side of the layer of transition metal dichalcogenide crystals;
a first electrode disposed in the first liquid;
a second liquid disposed on a second side of the layer of transition metal dichalcogenide crystals, wherein the first side is opposite the second side;
a second electrode disposed in the second liquid;
a voltage source in electrical communication with the first electrode and the second electrode such that the voltage source is configured to provide a voltage across the first electrode and the second electrode;
a current measuring device in electrical communication with the voltage source, the first electrode, and the second electrode; and
a control system configured to vary a voltage level of the voltage provided by the voltage source to maintain a constant average current level of a current measured by the current measuring device, wherein the current is an alternating current.
