Abstract

A device to electrochemically sequence DNA that includes a redox species includes at least one edge electrode, at least one stack of insulator material, and a pair of DNA translocation electrodes including a DNA translocation working electrode and a DNA translocation counter electrode, where the thickness of the at least one edge electrode is about 0.5 nanometers, and the thickness of the at least one stack of insulator material is about 10 nanometers. Methods of electrochemically sequencing a strand of DNA are also provided.
