  • Patent number: 10347389
    Abstract: This invention relates to a technique that uses an externally applied electric field to self-assemble monolayers of mixtures of particles into molecular-like hierarchical arrangements on fluid-liquid interfaces. The arrangements consist of composite particles which are arranged in a pattern. The structure of a composite particle depends on factors such as the relative sizes of the particles and their polarizabilities, and the electric field intensity. If the particles sizes differ by a factor of two or more, the composite particle has a larger particle at its core and several smaller particles form a ring around it. The number of particles in the ring and the spacing between the composite particles depend on their polarizabilities and the electric field intensity. Approximately same sized particles form chains in which positively and negatively polarized particles alternate, and when their polarizabilities are comparable they form tightly packed crystals.

  • Patent number: 10168278
    Abstract: An optical system and method for quantifying total protein in whole blood or other multi-phase liquids and colloidal suspensions uses refractometry without preliminary steps such as cell separation or centrifugation. A refractometer is integrated with a flow cell to enable the refractive index of a flowing sample to be measured based on a substantially cell free boundary layer of the sample that is present under certain flow conditions. Dimensions of the flow cell are selected to produce a cell-free layer in a flow of whole blood in which the cell free layer is thick enough to reduce scattering of light from the refractometer light source. A numerical method is used to compensate for scattering artifacts. The numerical compensation method is based on the slope and width of a peak in the derivative curve of an angular spectrum image of the flowing sample produced by refractometry.

  • Patent number: 9995662
    Abstract: The present invention provides methods, systems, assemblies, and articles for capturing single cells with a polymer capture film. In certain embodiments, the polymer capture films comprise a plurality of individual channels with top and bottom openings, where the channels are dimensioned such that a single cell is: i) is captured inside the channel, partially or substantially occluding the channel, when negative pressure is provided to the bottom opening; or ii) is captured by the top opening, but does not enter the channel, when negative pressure is provided to the bottom opening. In some embodiments, the channels of the polymer capture film align with the wells of a multi-well chip such that the cell, or the contents of the single cell, may be transferred to a corresponding well.
