Abstract: Molecules may be analyzed (e.g., sequencing of nucleic acid molecules) by tunneling recognition at a tunneling junction. Embodiments of the present invention may allow detecting individual nucleotides and the sequencing of a nucleic acid molecule using a tunneling junction. By labeling a specific nucleotide with a moiety, tunneling junctions may generate a signal with a suitable signal-to-noise ratio. The tunneling recognition uses a tunneling current that is mostly through the moiety rather than mostly through the nucleotide or a portion of the molecule of interest. Because a single nucleotide can be detected with a signal with a suitable signal-to-noise ratio resulting from the tunneling current passing through the moiety, embodiments of the present invention may allow for fast detection of nucleotides using a tunneling current.

Abstract: Provided are nanopore-based methods, compositions, and systems for assessing analyte-ligand interactions and analyte concentration in a fluid solution. The compositions include an analyte detection complex that is associated with a nanopore to form a nanopore assembly, the analyte detection complex including an analyte ligand. As a first voltage is applied across the nanopore assembly, the analyte ligand is presented to an analyte in the solution. As a second voltage that is opposite in polarity to the first voltage is applied across the nanopore assembly, the analyte binds to the analyte. By comparing the total number of analyte-ligand binding pairs to a control binding count, the concentration of the analyte can be determined. In other examples, further increasing the second voltage can result in dissociation of the analyte-ligand pair, from which a dissociation voltage—and hence a dissociation constant—can be determined.
