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.

Abstract: A DNA sequencing device and related methods, wherein the device includes a substrate, a nanochannel formed in the substrate, a first electrode positioned on a first side of the nanochannel, and a second electrode. The second electrode is positioned on a second side of the nanochannel opposite the first electrode and is spaced apart from the first electrode to form an electrode gap that is exposed in the nanochannel. At least a portion of first electrode is movable relative to the second electrode to decrease a size of the electrode gap.

Abstract: Apparatus and methods to identify nucleotides of a DNA strand. The method includes exposing the DNA strand to a first dye or peptide, attaching the first dye or peptide to a first type of nucleotide (A,T,C,G) of the DNA strand, the first dye or peptide changing a conductance of the first type of nucleotide to which the first dye or peptide is attached, and measuring a tunneling current signal for all nucleotides of the DNA strand, the changed conductance of the first type of nucleotide providing amplified tunneling current discrimination of the nucleotides of the DNA strand.

Abstract: Provided herein is a method, including creating a first pattern in a data region of a substrate, and creating a second pattern in a servo region of a substrate. A circumferential line pattern is created overlapping the first pattern to create rectangle-shaped protrusions in the data region of the substrate. A chevron pattern is created overlapping the second pattern to create chevron-derived protrusions in the servo region of the substrate.
