Abstract:
Apparatus and methods for analyzing single molecule and performing nucleic acid sequencing. An apparatus can include an assay chip that includes multiple pixels with sample wells configured to receive a sample, which, when excited, emits emission energy; at least one element for directing the emission energy in a particular direction; and a light path along which the emission energy travels from the sample well toward a sensor. The apparatus also includes an instrument that interfaces with the assay chip. The instrument includes an excitation light source for exciting the sample in each sample well; a plurality of sensors corresponding the sample wells. Each sensor may detect emission energy from a sample in a respective sample well. The instrument includes at least one optical element that directs the emission energy from each sample well towards a respective sensor of the plurality of sensors.
Abstract:
An active-source-pixel, integrated device capable of performing biomolecule detection and/or analysis, such as single-molecule nucleic acid sequencing, is described. An active pixel of the integrated device includes a sample well into which a sample to be analyzed may diffuse, an excitation source for providing excitation energy to the sample well, and a sensor configured to detect emission from the sample. The sensor may comprise two or more segments that produce a set of signals that are analyzed to differentiate between and identify tags that are attached to, or associated with, the sample. Tag differentiation may be spectral and/or temporal based. Identification of the tags may be used to detect, analyze, and/or sequence the biomolecule.

Abstract:
Methods of sequencing molecules based on luminescence lifetimes and/or intensities are provided. In some aspects, methods of sequencing nucleic acids involve determining the luminescence lifetimes, and optionally luminescence intensities, of a series of luminescently labeled nucleotides incorporated during a nucleic acid sequencing reaction.

Abstract:
Apparatus and techniques for electrokinetic loading of samples of interest into sub-micron-scale reaction chambers are described. Embodiments include an integrated device and related apparatus for analyzing samples in parallel. The integrated device may include at least one reaction chamber formed through a surface of the integrated device and configured to receive a sample of interest, such as a molecule of nucleic acid. The integrated device may further include electrodes patterned adjacent to the reaction chamber that produce one or more electric fields that assist loading the sample into the reaction chamber. The apparatus may further include a sample reservoir having a fluid seal with the surface of the integrated device and configured to hold a suspension containing the samples.
