Abstract:
1. A nanodevice comprising: a reservoir filled with a conductive fluid; a membrane formed to separate the reservoir in the nanodevice, the membrane including an electrode layer having a tunneling junction formed therein; wherein the membrane is formed to have a nanopore formed through one or more other layers of the membrane such that the nanopore is aligned with the tunneling junction of the electrode layer; and tips of the tunneling junction comprising at least one of an electroplated metal and an electroless metal, the at least one of the electroplated metal and the electroless metal at the tips including either a different material from the electrode layer or a same material as the electrode layer; wherein the tunneling junction of the electrode layer is narrowed to a narrowed size by electroplating or electroless deposition; wherein when a voltage is applied to the electrode layer, a tunneling current is generated by a base in the tunneling junction to be measured as a current signature for distinguishing the base; and wherein when an organic coating is formed on an inside surface of the tunneling junction, transient bonds are formed between the electrode layer and the base.
