  • Patent number: 11982649
    Abstract: A shear testing system and method of thermo-seepage-mechanical field and engineering disturbance coupling under deep and complex condition are provided. The shear testing system can be used in conjunction with an axial pressure application device to simplify the structure, save costs, and facilitate a triaxial confining pressure—temperature—axial pressure—torsional shear coupled test on a rock specimen. The shear testing system can achieve the following three purposes. First, the shear testing system can convert an axial pressure into a torsional shear force through a transmission mechanism of a power conversion assembly. Second, the shear testing system can apply an axial pressure to the rock specimen fixed between two specimen fixing heads, through a pressure shaft of an axial pressure mechanism. Third, the shear testing system can apply a triaxial confining pressure and a temperature field to the rock specimen.

  • Patent number: 11913867
    Abstract: An optofluidic device includes: a housing having an inlet port coupled to an inlet side and an outlet port coupled to an outlet side; and a microlens disposed within the housing between the inlet side and the outlet side. A fluid having a plurality of particles flows from the inlet side through the microlens to the outlet side. The optofluidic device further includes a light source configured to emit a light beam in a direction opposite flow direction of the fluid, the light beam defining an optical axis that is perpendicular to the microlens.

  • Publication number: 20230408501
    Abstract: Methods for detecting submolar concentrations of a target analyte in a sample are disclosed. These methods combine a process of biomarker to bead conversion with bead enrichment and simple visual, optical, or electrochemical detection of the presence of enriched beads to provide sensitive and inexpensive assay for detecting analytes in a sample. Devices for performing these methods are also disclosed.

  • Patent number: 11668676
    Abstract: The present disclosure provides methods, microfluidic devices, and systems for isolating target particles from a sample containing or suspected of containing the target particles. The methods, microfluidic devices, and systems disclosed herein facilitate affinity-based isolation of target particles in a microfluidic channel by translating the target particles to the side walls of the microfluidic channel where capture agents that bind to the target particles are immobilized.

  • Publication number: 20220404259
    Abstract: An optofluidic device includes: a housing having an inlet port coupled to an inlet side and an outlet port coupled to an outlet side; and a microlens disposed within the housing between the inlet side and the outlet side. A fluid having a plurality of particles flows from the inlet side through the microlens to the outlet side. The optofluidic device further includes a light source configured to emit a light beam in a direction opposite flow direction of the fluid, the light beam defining an optical axis that is perpendicular to the microlens.
