  • Patent number: 10526647
    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: 20190112650
    Abstract: This invention provides nucleoside polyphosphate analogues each of which comprises a tag comprising a plurality of Raman-scattering moieties; compounds comprising said nucleoside polyphosphate analogs. This invention also provides nucleotide polymerases with one or more attached and/or conjugated noble metal nanoparticles, wherein the noble metal nanoparticles are surface-enhanced Raman spectroscopy (SERS) substrates thereby creating a region of enhanced sensitivity for surface enhanced Raman spectroscopy (SERS) within or adjacent to the polymerase. This invention also provides a surface with regions of enhanced sensitivity for surface enhanced Raman spectroscopy comprising interspersed rough or nanostructured noble metal surface. This invention also provides methods for determining the sequence of a single stranded DNA or RNA polynucleotide using one or more of nucleoside polyphosphate analogues, polymerase with noble metal nanoparticles, and surface with noble metal.
