    Abstract: A device for high-throughput multi-parameter functional profiling of the same cells in multicellular settings and in isolation is provided. In certain aspects, an integrated microfluidic device for multi-parameter metabolic and other phenotypic profiling of live biological cells is useable with: 1) multicellular clusters or small biopsy tissue samples, 2) cultures of the constituent cells obtained after cluster/tissue dissociation, and 3) the same constituent single cells in isolation. The approach enables study of the effects of multicellular complexity, such as in response to treatment, pathogens, stress, or other factors concerning disease origination and progression. Measurements may be performed on single cells or multicellular populations or tissues in the same assay at the same time.

    Abstract: A method for preparing thin layers from liquid samples is disclosed. Such thin layers can be useful when analyzing samples with probes whose penetration length in these samples is short The method consists of squeezing a certain amount of a liquid sample between two approximately flat and parallel surfaces separated by a small distance then cooling down the liquid sample until it freezes in a way that the frozen sample adheres only to one of these two flat surfaces. Removing the non-adhered flat surface leaves the frozen sample layer with the thickness approximately equal to the initial distance between the two parallel surfaces.

  • Patent number: 10393725
    Abstract: A system and method that images biological samples and uses chromophores to analyze the imaged samples. The chromophore analysis can be done by itself or in conjunction with fluorophore analysis in High Content Imaging systems. To perform chromophore analysis the biological samples can be labeled with different chromophores and imaged using transmitted light that is at least partially absorbed by the chromophores. To also perform fluorophore analysis the samples can also be labeled with fluorophores that are excited by excitation light. The chromophore analysis and fluorophore analysis can be performed separately or concurrently using a High Content Imaging system. The system provides the expanded capability by illuminating the chromophore-labeled samples with transmitted light of different wavelengths and automatically detecting the images which represent the differential absorption of the colored lights by the sample.

  • Patent number: 9322052
    Abstract: A cartridge for conducting a chemical reaction includes a body having at least one flow path formed therein. The cartridge also includes a reaction vessel extending from the body for holding a reaction mixture for chemical reaction and optical detection. The vessel comprises a rigid frame defining the side walls of a reaction chamber. The frame includes at least one channel connecting the flow path to the chamber. The vessel also includes flexible films or sheets attached to opposite sides of the rigid frame to form opposing major walls of the chamber. In addition, at least two of the side walls are optically transmissive and angularly offset from each to permit real-time optical detection of analyte in the reaction chamber.

  • Patent number: 9267876
    Abstract: The present invention relates to a cell for optical analysis, wherein a flow space of a low depth is formed by attachment, using a simple double-coated tape without out special processing, of a micro flow channel through which a liquid sample passes, thereby enabling: a very easy manufacturing method; a reduction of manufacturing costs, thereby allowing the cell to be more widely used; a maintenance of a short path length of light with respect to the flow space in which the liquid sample flows, thereby enabling accurate optical analysis without diluting a sample with high absorbance; an expansion of a flow space region along the plane vertical to the light-passing direction, thereby enabling smoother optical analysis and improving the accuracy of optical analysis.

  • Patent number: 9074250
    Abstract: Cartridges for the isolation of a biological sample and downstream biological assays on the sample are provided, as are methods for using such cartridges. In one embodiment, a nucleic acid sample is isolated from a biological sample and the nucleic acid sample is amplified, for example by the polymerase chain reaction. The cartridges provided herein can also be used for the isolation of non-nucleic acid samples, for example proteins, and to perform downstream reactions on the proteins, for example, binding assays. Instruments for carrying out the downstream biological assays and for detecting the results of the assays are also provided.

  • Patent number: 9034651
    Abstract: This invention relates to methods and apparatus for determination of ion concentrations, particularly in downhole water from hydrocarbon wells, aquifers etc. It is useful in a wide range of applications, including predicting the formation of scale and fingerprinting waters from different sources. More particularly, the invention relates to the use of ligands whose electronic configuration is altered by the binding of the scaling ions within a water sample. These alterations are detected electrochemically by applying varying potential to electrodes and measuring current flow as potential is varied, from which is derived the concentration of scaling ions in the fluid.
