Apparatus and methods relating to DNA sequencing are provided. In one embodiment, a DNA sequencing device includes a nanochannel having a width that is approximately 0.3 nm to approximately 20 nm. A pair of electrodes having portions exposed to the nanochannel may form a tunneling current electrode (TCE) with an electrode gap of approximately 0.1 nm to approximately 2 nm, and more particularly about 0.3 nm to about 1 nm. In one embodiment, at least one of the pair of electrodes is formed as a suspended electrode. An actuator may be associated with the suspended electrode to displace it relative to the other electrode. In various embodiments, the nanochannel and/or the electrodes may be formed using thermal reflow processes to reduce the size of such features.

Method to fabricate a nanochannel for DNA sequencing based on narrow trench patterning process

A DNA sequencing device, and related methods, include a nanopore or nanochannel structure, and a nanoelectrode. The nanoelectrode includes electrode members having free ends exposed within the nanopore or nanochannel structure, an electrode gap defined between of the free ends, and plated portions formed on the free ends to provide a reduced sized for the electrode gap.

Fabrication of a nanochannel for DNA sequencing using electrical plating to achieve electrode gap

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.

Fabrication of nanochannel with integrated electrodes for DNA sequencing using tunneling current

A DNA sequencing device, and related method, which include an electrode and a plurality of spaced apart alignment structures. The electrode defines an electrode gap, the electrode being operable to detect a change in tunneling current as a DNA strand passes through the electrode gap. The plurality of spaced apart alignment structures are arranged to position nucleotides of the DNA strand in a predetermined orientation as the DNA strand passes through the electrode gap.

Nanostructures to control DNA strand orientation and position location for transverse DNA sequencing

A DNA sequencing device, and related methods, include a nanochannel sized to receive a DNA strand, a first electrode member exposed within the nanochannel, and a second electrode member exposed within the nanochannel and spaced apart from the first electrode to form an electrode gap. The second electrode member has a wedge shaped profile, and the first and second electrode members are operable to detect a change in electronic signal as the DNA strand passes through the electrode gap.

Fabrication of a wedge shaped electrode for enhanced DNA sequencing

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.

Apparatus and methods to sequence DNA. A DNA sequencing device includes a passage, a first electrode, and a second electrode. The passage has a width and a length. The first and second electrodes are exposed within the passage and spaced apart from each other to form an electrode gap. The electrode gap is no greater than about 2 nm.

Direct sequencing device with a top-bottom electrode pair

The embodiments disclose a stack feature of a stack configured to confine optical fields within and to a patterned plasmonic underlayer in the stack configured to guide light from a light source to regulate optical coupling.

Patterned plasmonic underlayer

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.
