Provided herein are compositions and systems for use in polymerase-dependent, nucleotide transient-binding methods. The methods are useful for deducing the sequence of a template nucleic acid molecule and single nucleotide polymorphism (SNP) analyses. The methods rely on the fact that the polymerase transient-binding time for a complementary nucleotide is longer compared to that of a non-complementary nucleotide. The labeled nucleotides transiently-binds the polymerase in a template-dependent manner, but does not incorporate. The methods are conducted under any reaction condition that permits transient binding of a complementary or non-complementary nucleotide to a polymerase, and inhibits nucleotide incorporation.

Nucleotide transient binding for sequencing methods

A scanning detection system is provided wherein emissions from locations in a flow cell are detected. In some embodiments, the system can comprise an excitation source, a photocleavage source, and modulating optics configured to cause an excitation beam generated by the excitation source to irradiate a first group of the fixed locations and to cause a photocleavage beam generated by the photocleavage source to irradiate a second group of the fixed locations, which is separate and apart from the first group of fixed locations. Methods of detecting sequencing reactions using such a system are also provided.

Scanning system and method for imaging and sequencing

A method for sequencing a nucleic acid template includes forming a nanowire assembly including a semiconductor nanowire and a probe covalently bound to the semiconductor nanowire; contacting the nanowire assembly with a template nucleic acid; contacting the nucleic acid duplexes with an extension nucleic acid, the extension nucleic acid joined to the probe; disrupting the nucleic acid duplexes; and measuring an electrical characteristic of a nanowire assembly of the set of nanowire assemblies.

Nanowire-based system for analysis of nucleic acids

In some embodiments, an analyte detection system is provided that includes a nanochannel, an electrode arrangement, and a plurality of nanoFET devices disposed in the nanochannel. A plurality of nucleic acid base detection components can be used that include a plurality of nanopores, a plurality of nanochannels, a plurality of hybridization probes, combinations thereof, and the like. According to other embodiments of the present teachings, different coded molecules are hybridized to a target DNA molecule and used to detect the presence of various sequences along the target molecule. A kit including mixtures of coded molecules is also provided. In some embodiments, devices including nanochannels, nanopores, and the like, are used for manipulating movement of DNA molecules, for example, in preparation for a DNA sequencing detection. Nanopore structures and methods of making the same are also provided as are methods of nucleic acid sequencing using the nanopore structures. Surface-modified nanopores are provided as are methods of making them. In some embodiments, surfaced-modified nanopores for slowing the translocation of single stranded DNA (ssDNA) through the nanopore are provided, as are nanopores configured to detect each of a plurality of different bases on an ssDNA strand.

DNA sequencing methods and detectors and systems for carrying out the same

System for detection and/or analysis of nucleic acids using nanowires to detect covalent modification of nucleic acids.

A scanning detection system is provided in which emissions from locations in a flow cell are detected. In some embodiments, the system can include an excitation source, a photocleavage source, and modulating optics configured to cause an excitation beam generated by the excitation source to irradiate a first group of the fixed locations and to cause a photocleavage beam generated by the photocleavage source to irradiate a second group of the fixed locations, which is separate and apart from the first group of fixed locations. Methods of detecting sequencing reactions using such a system are also provided.

A system and method for analyzing nucleic acids is presented herein. The system can include a nanowire assembly including a plurality of nanowires. In some embodiments, at least two nanowires can be coupled to a different probe corresponding to a different sequence version of a polymorphism. The system can include a reagent delivery system capable of delivering a template polymorphic nucleotide, an extension nucleic acid, and an enzyme to the nanowire assembly. The system can include an electrical detector configured to measure an electrical characteristic of the nanowire assembly and/or a controller in communication with the reagent delivery system. In some embodiments, the electrical detector can be configured to collect data corresponding to changes in the electrical characteristic in response to contact with the template polymorphic nucleotide, the extension nucleic acid, and the enzyme.
