  • Patent number: 11092589
    Abstract: A method of forming a nanopore in a lipid bilayer is disclosed. A nanopore forming solution is deposited over a lipid bilayer. The nanopore forming solution has a concentration level and a corresponding activity level of pore molecules such that nanopores are substantially not formed un-stimulated in the lipid bilayer. Formation of a nanopore in the lipid bilayer is initiated by applying an agitation stimulus level to the lipid bilayer. In some embodiments, the concentration level and the corresponding activity level of pore molecules are at levels such that less than 30 percent of a plurality of available lipid bilayers have nanopores formed un-stimulated therein.

  • Publication number: 20200377944
    Abstract: This disclosure provides chips, systems and methods for sequencing a nucleic acid sample. Tagged nucleotides are provided into a reaction chamber comprising a nanopore in a membrane. An individual tagged nucleotide of the tagged nucleotides can contain a tag coupled to a nucleotide, which tag is detectable with the aid of the nanopore. Next, an individual tagged nucleotide of the tagged nucleotides can be incorporated into a growing strand complementary to a single stranded nucleic acid molecule derived from the nucleic acid sample. With the aid of the nanopore, a tag associated with the individual tagged nucleotide can be detected upon incorporation of the individual tagged nucleotide. The tag can be detected with the aid of the nanopore when the tag is released from the nucleotide.

  • Publication number: 20200308641
    Abstract: 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.

    Abstract: Apparatuses and methods for producing crystalline materials from plant extracts are described herein. In one example, an apparatus for producing crystalline material from plant extract can include a vessel comprising an inner volume configured to receive a plant extract. The apparatus can include a desiccant chamber fluidly connected to the vessel. The desiccant chamber can house a desiccant material. The desiccant material can absorb water vapor from the plant extract and thereby promote growth of crystalline material.

  • Publication number: 20190367977
    Abstract: Described herein are methods and devices for capturing and determining the identity of molecules using nanopores. The molecules can be counted, sorted and/or binned rapidly in a parallel manner using a large number of nanopores (e.g., 132,000 nanopores reading 180 million molecules in 1 hour). This fast capture and reading of a molecule can be used to capture probe molecules or other molecules that have been generated to represent an original, hard to detect molecule or portions of an original molecule. Precise counting of sample molecules or surrogates for sample molecules can occur. The methods and devices described herein can, among other things, replace flow cytometers and other counting instruments (e.g., while providing increased precision and throughput relative to a flow cytometer).
