  • Patent number: 10761000
    Abstract: In a liquid stirring method, after a second liquid is discharged into a reaction container accommodating a first liquid from a dispensing probe provided with a dispensing tip at the leading end thereof, a mixture of the first liquid and second liquid in the container is stirred by being sucked out and discharged by the dispensing probe. The number of stirrings through sucking out and discharging is changed according to the total volume of the first liquid and second liquid. If the total volume of the first liquid and second liquid is below a preset threshold, sucking out and discharging is repeated for a prescribed number of times.

  • Patent number: 10710075
    Abstract: Methods and devices for concentrating target cells using dielectrophoresis (DEP) are disclosed. The method allows relatively high throughput of sample through a microfluidic device in order to allow rapid capture of target cells even when they are present in low concentrations within the sample. The method utilizes multiple chambers through which samples will flow, the chambers arranged such that the first capture area has a larger area and faster flow rate than a second chamber, the second chamber being positioned downstream of the first capture area and being smaller with a slower flow rate to further concentrate the material captured in the first capture area.

  • Patent number: 10633586
    Abstract: Polydentate polycyclic compounds of various formulas are disclosed herein. The compounds are useful for ratiometric luminescence. Significantly, the compounds will luminesce at different wavelengths/colors, depending on the analyte (metal ion, acid, or boron-containing compound) it is combined with. Thus, a single compound can provide different luminescent outputs based on the analyte, rather than requiring an entire set of structurally different compounds to detect each analyte or to generate a desired color output.

  • Patent number: 10534006
    Abstract: A microfluidic, chip-based assay device has been developed for measuring physical properties of an analyte (particularly, whole blood or whole blood derivatives). The technologies can be applied to measure clotting times of whole blood or blood derivatives, determine the effects of anticoagulant drugs on the kinetics of clotting/coagulation, as well as evaluate the effect of anticoagulant reversal agents. These technologies can additionally be used to optimize the dosage of anticoagulation drugs and/or their reversal agents. The assay is independent of the presence of anticoagulant; clotting is activated by exposure of the blood sample in the device to a glass (or other negatively charged material such as oxidized silicon) surface, which activates the intrinsic pathway and can be further hastened by the application of shear flow across the activating materials surface.
