  • Patent number: 11965210
    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.

  • Publication number: 20240011970
    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.
