  • Publication number: 20160222444
    Abstract: The present disclosure provides method and systems for improving nanopore-based analyses of polymers. The disclosure provides methods for selectively modifying one or more monomeric subunit(s) of a kind a pre-analyte polymer that results polymer analyte with a modified subunit. The polymer analyte produces a detectable signal in a nanopore-based system. The detectable signal, and/or its deviation from a reference signal, indicates the location of the modified subunit in the polymer analyte and, thus, permits the identification of the subunit at that location in the original pre-analyte polymer.

  • Publication number: 20150344945
    Abstract: Compositions, systems, and methods for detecting events are provided. A composition can include a nanopore including a first side, a second side, and an aperture extending through the first and second sides; and a permanent tether including head and tail regions and an elongated body disposed therebetween. The head region can be anchored to or adjacent to the first or second side of the nanopore. The elongated body including a reporter region can be movable within the aperture responsive to a first event occurring adjacent to the first side of the nanopore. For example, the reporter region is translationally movable toward the first side responsive to the first event, then toward the second side, then toward the first side responsive to a second event. The first event can include adding a first nucleotide to a polynucleotide. The second event can include adding a second nucleotide to the polynucleotide.

  • Publication number: 20150191782
    Abstract: The present disclosure provides methods and reagents for improving nanopore-based analyses of polymers. Specifically, the disclosure provides a method of analyzing a polymer that includes a polymer analyte that contains an end domain that has at least one charged moiety. The disclosure also provides a method of increasing the interaction rate between a polymer analyte and a nanopore, wherein the polymer analyte contains an end domain that has at least one charged moiety. The disclosure also provide compositions for use with the described methods, including adapter compositions that contain charged moieties, such as phosphate or sulfate groups, and that are configured to being linked to an polymer analyte domain.

  • Patent number: 8842291
    Abstract: Systems and method are disclosed for measuring small angular deflections of a target using weak value amplification. A system includes a beam source, a beam splitter, a target reflecting surface, a photodetector, and a processor. The beam source generates an input beam that is split into first and second beams by the beam splitter. The first and second beams are propagated to the target reflecting surface, at least partially superimposed at the target reflecting surface, and incident to the target reflecting surface normal to the target reflecting surface. The first beam is reflected an additional even number of times during propagation to the photodetector. The second beam is reflected an additional odd number of times during propagation to the photodetector. The first and second beams interfere at the photodetector so as to produce interference patterns. The interference patterns are interpreted to measure angular deflections of the target reflecting surface.
