  • Publication number: 20180030524
    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.

  • Patent number: 9605307
    Abstract: Techniques for forming a nanopore in a lipid bilayer are described herein. In one example, an agitation stimulus level such as an electrical agitation stimulus is applied to a lipid bilayer wherein the agitation stimulus level tends to facilitate the formation of nanopores in the lipid bilayer. In some embodiments, a change in an electrical property of the lipid bilayer resulting from the formation of the nanopore in the lipid bilayer is detected, and a nanopore has formed in the lipid bilayer is determined based on the detected change in the lipid bilayer electrical property.

  • Publication number: 20160327507
    Abstract: A biochip for molecular detection and sensing is disclosed. The biochip includes a substrate. The biochip includes a plurality of discrete sites formed on the substrate having a density of greater than five hundred wells per square millimeter. Each discrete site includes sidewalls disposed on the substrate to form a well. Each discrete site includes an electrode disposed at the bottom of the well. In some embodiments, the wells are formed such that cross-talk between the wells is reduced. In some embodiments, the electrodes disposed at the bottom of the wells are organized into groups of electrodes, wherein each group of electrodes shares a common counter electrode. In some embodiments, the electrode disposed at the bottom of the well has a dedicated counter electrode. In some embodiments, surfaces of the sidewalls are silanized such that the surfaces facilitate the forming of a membrane in or adjacent to the well.
