Abstract:
The invention relates to devices and methods for nanopore sequencing. The invention includes arrays of nanopores having incorporated electronic circuits, for example, in CMOS. In some cases, the arrays of nanopores comprise resistive openings for isolating the electronic signals for improved sequencing. Methods for controlling translocation of through the nanopore are disclosed.
Abstract:
Methods for non-random loading of single analyte molecules into array structures are provided. The methods allow for distribution of a population of target molecules into a plurality of size confined regions such as wells. Sizing moieties are linked to individual target molecules. The sizing moieties are of sufficient size, relative to the size-confined reaction or observation regions, such that only a selected number of sizing moieties will fit into the size confined regions. The confined regions and the sizing moieties or target molecules comprise a selected charge that allow for controlling the loading of the sizing moities.
Abstract:
Methods of producing substrates having selected active chemical regions by employing elements of the substrates in assisting the localization of active chemical groups in desired regions of the substrate. The methods may include optical, chemical and/or mechanical processes for the deposition, removal, activation and/or deactivation of chemical groups in selected regions of the substrate to provide selective active regions of the substrate.

Abstract:
Labeled reactant compositions, and particularly labeled nucleic acid reaction compositions, that include structural components that maintain potentially damaging labeling components sufficiently distal from the reactant portion of the molecule such that damaging effects of the label group on other reaction components, such as enzymes, are reduced, minimized and/or eliminated.
Abstract:
Real time redox sequencing methods, devices, and systems are described. Arrays of redox devices comprising one or two electrodes are used to provide sequence information about a template nucleic acid in a polymerase-template complex bound proximate to the electrode(s). A sequencing reaction mixture comprising nucleotide analogs comprising redox labels is introduced to the array of redox devices under conditions of polymerase mediated nucleic acid synthesis. The time sequence of incorporation of nucleotide analogs is determined by electrochemically identifying the redox labels of the nucleotide analogs that are incorporated into the growing strand.
