Fluidic devices and methods are provided.

Fluidic systems comprising an incubation channel, including fluidic systems formed by molding

Fluidic devices and methods involving incubation and/or mixing of assay components are provided. In some embodiments, a biological and/or chemical assay may be performed in a fluidic device. The fluidic device may be designed to allow for controlled incubation and/or mixing of two or more assay components. In some such embodiments, the fluidic device may comprise an incubation channel having a relatively large cross-sectional dimension in fluid communication with a detection channel. The incubation channel may allow for adequate mixing and/or incubation of two or more assay components prior to analysis of the assay. In some embodiments, fluidic devices for performing a vitamin D assay are provided.

Fluidic systems involving incubation of samples and/or reagents

Articles and methods for collecting and/or facilitating transfer of fluids are generally provided. In some embodiments, an article comprises a fluid collection region for introducing a fluid, such as a sample (e.g., blood sample) or a reagent, into a fluidic system. The articles and methods described herein may be useful for facilitating the filling of relatively small channels with a fluid, such as channels of a microfluidic device. The articles and methods may, for example, interface with a patient sample (e.g., a droplet of blood), or with a macroscopic fluid source such as a pipette or syringe. In certain embodiments, articles and methods described herein may increase the ease of collecting a fluidic sample from a patient, prevent or reduce spillage of the fluidic sample, reduce contamination of a fluidic sample, and/or prevent or reduce air from entering a fluidic sample or device compared to certain existing fluid collection devices.

Fluid collection device and related methods

Fluidic devices and methods associated with mixing of fluids in fluidic devices are provided. In some embodiments, a method may involve the mixing of two or more fluids in a channel segment of a fluidic device. The fluids may be in the form of, for example, at least first, second and third fluid plugs, composed of first, second, and third fluids, respectively. The second fluid may be immiscible with the first and third fluids. In certain embodiments, the fluid plugs may be flowed in series in the channel segment, e.g., in linear order, causing the first and third fluids to mix without the use of active components such as mixers. The mixing of fluids in a channel segment as described herein may allow for improved performance and simplification in the design and operations of fluidic devices that rely on mixing of fluids.

Mixing of fluids in fluidic systems

The fluidic device may be designed to allow for controlled incubation and/or mixing of two or more assay components. In some such embodiments, the fluidic device may include an incubation channel having a relatively large cross-sectional dimension in fluid communication with a detection channel. The incubation channel may allow for adequate mixing and/or incubation of two or more assay components prior to analysis of the assay. In certain embodiments, the detection channel may be used to provide feedback on the extent of incubation and/or mixing. Based on the feedback, one or more component of the fluidic system may be regulated to allow the requisite degree of mixing and/or incubation to be achieved.

Multi-layered sample cassette

Fluidic devices and methods associated with mixing of fluids in fluidic devices are provided. In some embodiments, a method may involve the mixing of two or more fluids in a channel segment of a fluidic device. The fluids may be in the form of, for example, at least first, second and third fluid plugs, composed of first, second, and third fluids, respectively.
