    摘要: A nanopore cell includes a conductive layer and a working electrode disposed above the conductive layer and at the bottom of a well into which an electrolyte may be contained, such that at least a portion of a top base surface area of the working electrode is exposed to the electrolyte. The nanopore cell further includes a first insulating wall disposed above the working electrode and surrounding a lower section of a well, and a second insulating wall disposed above the first insulating wall and surrounding an upper section of the well, forming an overhang above the lower section of the well. The upper section of the well includes an opening that a membrane may span across, and wherein a base surface area of the opening is smaller than the at least a portion of the top base surface area of the working electrode that is exposed to the electrolyte.

    摘要: This disclosure provides systems and methods for attaching nano pore-detectable tags to nucleotides. The disclosure also provides methods for sequencing nucleic acids using the disdosed tagged nudeotides. Provided herein are nudeotides with attached tags and methods for attaching tags to nudeotides. The tags can be attached by chemical reactions, such as "dick chemistry". In an aspect, the present disdosure provides a tagged nudeotide, comprising: (a) a poly-phosphate moiety having a terminal phosphate; and (b) a tag covalently coupled to the terminal phosphate of the nudeotide by a triazole, a 1,2-diazine, a disulfide, a secondary amine, a hydrazone, a thio-acetamide, or a maleimide-thioadduct.

    摘要: This disclosure provides systems and methods for molecular identification and polymer (e.g., nucleic acid) sequencing using nanopores. The polymer may be passed through or in proximity to the nanopore and various subunits of the polymer may affect the current flowing through the nanopore. The various subunits may be identified by measuring the current at a plurality of voltages applied across the nanopore and/or membrane. In some cases, the polymerization of tagged nucleotides presents tag molecules to the nanopore that can be identified by measuring the current at a plurality of voltages applied across the nanopore and/or membrane. Also provided herein are systems and methods for sequencing both the sense and anti-sense strand of a double stranded nucleic acid molecule with a nanopore and methods for using ribonucleic acid (RNA) speed bump molecules to slow the passage of a nucleic acid molecule through or in proximity to a nanopore.

    摘要: Techniques for manipulating a molecule in a nanopore embedded in a lipid bilayer are described. In one example, an acquiring electrical stimulus level is applied across a lipid bilayer wherein a region of the lipid bilayer containing the nanopore is characterized by a resistance and wherein the acquiring electrical stimulus level tends to draw the molecule from a surrounding fluid into the nanopore, a change in the resistance of the lipid bilayer resulting from the acquisition of at least a portion of a molecule into the nanopore is detected, the acquiring electrical stimulus level is changed to a holding electrical stimulus level wherein the portion of the molecule remains in the nanopore upon the changing of the acquiring electrical stimulus level to the holding electrical stimulus level.
