  • Publication number: 20110204219
    Abstract: The present invention generally relates to mass spectrometry and related techniques, and in some cases, to determining single species using mass spectrometry. In certain instances, polymers such as DNA or RNA can also be sequenced. Certain embodiments of the invention relate to passing a polymer, such as DNA, RNA, a protein, a polypeptide, a polysaccharide, etc., through a pore and cleaving the polymer in sequence. For instance, the polymer may be cleaved using a laser or an electric field. In some embodiments, a property of at least one subunit of a polymer is determined using mass spectrometry. In some embodiments, a single ion (which may be a subunit of a polymer, or an ion based on another species) can be isolated in a mass spectrometer and a signal generated from the single ion.

  • Publication number: 20110059904
    Abstract: The invention provides serum-based, diagnostic, biological assays for predicting disorders of pregnancy resulting from poor trophoblast and/or placental ischemia, including preeclampsia. Serum samples from such subjects exhibit an ability to disrupt the architecture involving fetal trophoblasts and maternal endothelial cells in a three-dimensional, dual cell co-culture system provided herein, in contrast to normal pregnancy serum samples. Based on these distinctions, the assays are employed to predict pregnancy outcomes as early as first trimester.

  • Patent number: 7894070
    Abstract: Disclosed is a method for characterizing a sample having a structure disposed on or within the sample, comprising the steps of applying a first pulse of light to a surface of the sample for creating a propagating strain pulse in the sample, applying a second pulse of light to the surface so that the second pulse of light interacts with the propagating strain pulse in the sample, sensing from a reflection of the second pulse a change in optical response of the sample, and relating a time of occurrence of the change in optical response to at least one dimension of the structure.

  • Publication number: 20110036171
    Abstract: An optical-acoustic transducer structure includes at least one metal or semiconducting film in which a part of a pump light pulse is absorbed to generate a sound pulse; and at least one dielectric film. The thicknesses and optical properties of the at least one metal or semiconducting film and the at least one dielectric film are selected so that a returning sound pulse results in a measurable change in the optical reflectivity and/or some other optical characteristic of the transducer structure. The transducer structure includes a resonant cavity, and an output surface that is shaped so as to provide no significant focusing of generated sound waves when the sound waves are launched towards a surface of the sample.

  • Publication number: 20100323262
    Abstract: The present invention provides geometric arrangements for channels through which liquids or other fluids can be made to flow, for enhanced performance of fuel cells or other chemical or biochemical reactors or analyzers. Systems and methods including these improved geometries are described herein for enhanced performance of a variety of devices. Specifically, in one set of embodiments, the reactors comprise one or more microchannels comprising a tapered cross-sectional area and at least one reactive surface portion. By flowing a liquid comprising one or more reactants through the channel such that the cross-sectional area decreases in a downstream direction, relatively more reactant may be supplied to the wall at downstream positions relative to the amount that would be supplied in a system without a tapered cross-section. In some embodiments, the microchannel may be constructed and arranged such that the amount of reactant supplied to the wall conforms to a predetermined distribution.
