  • Patent number: 10745748
    Abstract: In some embodiments, a variety of devices and methods for conducting microfluidic analyses are utilized herein, including devices that can be utilized to conduct thermal cycling reactions such as nucleic acid amplification reactions. The devices include elastomeric components; in some instances, much or all of the device is composed of elastomeric material. Amplification products (amplicons) can be detected and distinguished (whether isolated in a reaction chamber or at any subsequent time) using routine methods for detecting nucleic acids. An example of a detection method includes hybridization to arrays of immobilized oligo or polynucleotides.

  • Patent number: 10527171
    Abstract: Disclosed herein are methods, devices, and systems for fluidic handling. In some embodiments, a gasket for providing a fluidic interface with a flowcell includes an inner cavity extending distally from a proximal end of the gasket, the inner cavity being defined by a plurality of inner surfaces sections, an inlet port positioned at a distal end of the inner cavity, an outlet port positioned at a distal end of the gasket, and a cannula extending between the inlet port and the outlet port; wherein at least some of the plurality of inner surface sections are tapered towards the distal end of the gasket to direct a pipette tip received within the gasket towards the inlet port of the gasket.

  • Publication number: 20190153511
    Abstract: An apparatus for imaging one or more selected fluorescence indications from a microfluidic device. The apparatus includes an imaging path coupled to least one chamber in at least one microfluidic device. The imaging path provides for transmission of one or more fluorescent emission signals derived from one or more samples in the at least one chamber of the at least one microfluidic device. The chamber has a chamber size, the chamber size being characterized by an actual spatial dimension normal to the imaging path. The apparatus also includes an optical lens system coupled to the imaging path. The optical lens system is adapted to transmit the one or more fluorescent signals associated with the chamber.
