Embodiments include assay devices within a single use, disposable cassette for biochemical assays with at least one fluid well and at least one capillary valve. The capillary valve in combination with motion of porous sheets within the assay leads to addition of liquid reagents at different times to the assay although a user adds the liquid reagents to the cassette simultaneously.

Assay structures for multi-step biochemical assays

The present disclosure relates to a sample assessment device. By way of example, the sample assessment device may include a substrate including a sample application region; an amplification region comprising a plurality of amplification reagents; a waste region comprising an entrance fluidically coupled to the amplification region and extending away from the amplification region; and a detection region spaced apart from the amplification region. The sample assessment device may also include a valve coupled to the substrate and configured to separate the amplification region from the detection region in a closed configuration, wherein the amplification region and the valve are positioned on the sample assessment device between the sample application region and the detection region and wherein the sample assessment device is configured to permit lateral flow from the amplification region to the detection region when the valve is in an open configuration.

Amplification and detection of nucleic acids

The present technology is directed to capillarity-based devices for performing chemical processes and associated system and methods. In one embodiment, for example, a device can include a porous receiving element having an input region and a receiving region, a first fluid source and a second fluid source positioned within the input region of the receiving element; wherein the first fluid source is positioned between the second fluid source and the receiving region, and wherein, when both the first and second fluid sources are in fluid connection with the input region, the device is configured to sequentially deliver the first fluid and the second fluid to the receiving region without leakage.

Sequential delivery of fluid volumes and associated devices, systems and methods

Temperature-actuated valves, devices including temperature-actuated valves, and related methods are described. In an embodiment, the temperature-actuated valve includes a heat-shrink film defining a perforation extending at least partially in a first direction. In an embodiment, the temperature-actuated valve is configured to open when a portion of the heat-shrink film including the perforation is heated above a threshold temperature to contract the heat-shrink film along a second direction perpendicular to the first direction to define an aperture, in an open configuration, providing a fluid a path through the heat-shrink film. In an embodiment, the temperature-actuated valve includes a leakage-mitigation feature configured to limit fluid flow through the perforation when the valve is in a closed configuration.
