Abstract: A DNA sequencing device and methods of making. The device includes a pair of electrodes having a spacing of no greater than about 2 nm, the electrodes being exposed within a nanopore to measure a DNA strand passing through the nanopore. The device can be made by depositing a conductive layer over a sacrificial channel and then removing the sacrificial channel to form the electrode gap.
