Abstract
A nanodevice includes a reservoir filled with conductive fluid and a membrane separating the reservoir. A nanopore is formed through the membrane having electrode layers separated by insulating layers. A certain electrode layer has a first type of organic coating and a pair of electrode layers has a second type. The first type of organic coating forms a motion control transient bond to a molecule in the nanopore for motion control, and the second type forms first and second transient bonds to different bonding sites of a base of the molecule. When a voltage is applied to the pair of electrode layers a tunneling current is generated by the base in the nanopore, and the tunneling current travels via the first and second transient bonds formed to be measured as a current signature for distinguishing the base. The motion control transient bond is stronger than first and second transient bonds.
