  • Patent number: 10845284
    Abstract: A droplet-based microfluidic rheometer system and method of use for real-time viscosity monitoring of blood coagulation is disclosed. Droplets of blood samples are generated in a microfluidic rheometer, and the size of the droplets is highly correlated to the sample viscosity. The size of the droplets can be determined optically using an inverted light microscope and a camera or using electrodes. The microfluidic rheometer systems provides viscosity measurements in less than a second and consumes less than 1?{umlaut over (?)} blood or plasma over an hour period. The viscosity measurements may be displayed and transmitted to the Internet or cloud storage.

  • Patent number: 10828638
    Abstract: An in vitro microfluidic “organ-on-chip” is described herein that mimics the structure and at least one function of specific areas of the epithelial system in vivo. In particular, a multicellular, layered, microfluidic culture is described, allowing for interactions between lamina propria-derived cells and the associated tissue specific epithelial cells and endothelial cells. This in vitro microfluidic system can be used for modeling inflammatory tissue, e.g., autoimmune disorders involving epithelia and diseases involving epithelial layers. These multicellular, layered microfluidic “organ-on-chip”, e.g. “epithelia-on-chip” further allow for comparisons between types of epithelia tissues, e.g., lung (Lung-On-Chip), bronchial (Airway-On-Chip), skin (Skin-On-Chip), cervix (Cervix-On-Chip), blood brain barrier (BBB-On-Chip), etc., in additional to neurovascular tissue, (Brain-On-Chip), and between different disease states of tissue, i.e. healthy, pre-disease and diseased areas.

  • Patent number: 10830672
    Abstract: The present invention provides an apparatus for collecting and detecting liquid samples comprising a first chamber and a second chamber. The first chamber is used for collecting liquid samples for initial detection, and the second chamber is used for collecting liquid samples for second confirmatory detection. The first chamber and second chamber of the apparatus are detachable. When a second confirmatory detection is necessary, the second chamber can be separated from the first chamber, and then sent to a detection agency for confirmatory detection. It can avoid the contamination of liquid samples caused by contacting with test strip of a traditional apparatus; thus, it can effectively reduce the space required for storing liquid samples and greatly reduce the risk of leakage of liquid sampled during transportation.

  • Patent number: 10792658
    Abstract: A microfluidic device can include a base an outer surface of which forms one or more enclosures for containing a fluidic medium. The base can include an array of individually controllable transistor structures each of which can comprise both a lateral transistor and a vertical transistor. The transistor structures can be light activated, and the lateral and vertical transistors can thus be photo transistors. Each transistor structure can be activated to create a temporary electrical connection from a region of the outer surface of the base (and thus fluidic medium in the enclosure) to a common electrical conductor. The temporary electrical connection can induce a localized electrokinetic force generally at the region, which can be sufficiently strong to move a nearby micro-object in the enclosure.

  • Patent number: 10788451
    Abstract: An analysis instrument comprises plural modules connected together over a data network, each module comprising an analysis apparatus operable to perform biochemical analysis of a sample. Each module comprises a control unit that controls the operation of the analysis apparatus. The control units are addressable to select an arbitrary number of modules to operate as a cluster for performing a common biochemical analysis. The control units communicate over the data network, repeatedly during the performance of the common biochemical analysis, to determine the operation of the analysis apparatus of each module required to meet the global performance targets, on the basis of measures of performance derived from the output data produced by the modules. The arrangement of the instrument as modules interacting in this manner provides a scalable analysis instrument.

  • Patent number: 10780438
    Abstract: An interfacial technique utilizes hydrodynamic micro-vortices to perform (i) high efficiency single cell encapsulation and (ii) size-selective capturing of cells based on their sizes in a single microfluidic device. A notable feature of this technique is that it can perform high efficiency single cell encapsulation at low cell concentrations, and this technique is all passive, controlled only by the flow rates of the two phases and does not require complex structures or on-chip active devices. Single bead/cell encapsulation was demonstrated at 50% efficiency, which is at least 10 times greater than the random encapsulations at the introduced cell concentrations. Also demonstrated is the selective trapping of cells based on their sizes. This present technique expands the capabilities of droplet microfluidics for applications ranging from single cell genomics, proteomic assays to sample preparation.
