Abstract: A first wafer has a first stop layer deposited on a substrate, the substrate used to form a base support structure. A second wafer has a second stop layer deposited on a sacrificial substrate, and a filter layer deposited on the second stop layer. A rib layer is deposited on one of: the first stop layer of the first layer; or a third stop layer that is deposited over the filter layer. A rib pattern is formed in the rib layer. The first and second wafers are flip bonded such that the rib pattern is joined between the filter layer and the first stop layer. Elongated voids are formed within the filter layer. The base support structure is formed within the substrate of the first wafer such that there is a fluid flow path between the base support structure, the rib layer, and the elongated voids of the filter layer.

Abstract: A method of manufacturing a synthetic nanopore device for DNA sequencing disclosed herein includes providing a base template, forming a guiding layer on top of the base template, and forming a photoresist layer on top of the guiding layer. The photoresist layer is patterned, and the guiding layer is etched for form a guiding pattern. The photoresist layer is removed to form a guiding template and a self-assembled monolayer is deposited on at least a portion of the guiding template to form a patterned template. The patterned template is exposed to one or more etch processes to form a nanoimprint lithography template. A membrane is imprinted with the nanoimprint lithography template to form an array of nanopores in the membrane.

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.
