The system further includes a flow control system comprising a manifold having a plurality of ports configured to fluidically couple to the plurality of wells, and one or more containment structures configured to contain carrier fluid and fluidically couple to the ports. The flow control system further includes a cradle configured to removably receive the substrate. The flow control system is configured to transmit pressure differential, via the manifold, to the plurality of wells so as to cause a plurality of sample volumes held by at least some wells of the plurality of wells to flow through respective flow channels and cause the carrier fluid to flow through the flow channels and form a plurality of droplets of the plurality of sample volumes separated by the carrier fluid.

Abstract: Assemblies, systems, and methods for isolation of target material are provided. In various embodiments, an assembly for target material isolation includes a housing having an upper portion and a lower portion together defining an inner chamber. The inner chamber includes a semi-toroidal shape and the semi-toroidal shape defines a longitudinal axis. The assembly further includes one or more fluidic connection from the exterior of the housing to the inner chamber. An isolation material (e.g., polymer wool and/or magnetic beads) may be disposed within the inner chamber. A system includes a configured to fit at least a portion of the housing and releasably couple the assembly. Upon activation of the motor, the assembly may rotate about the longitudinal axis. An angle of the platform may be adjustable to thereby change the angle of the longitudinal axis about which the assembly rotates.

Abstract: A bridge (30) comprises a first inlet port (31) at the end of a capillary, a narrower second inlet port (32) which is an end of a capillary, an outlet port (33) which is an end of a capillary, and a chamber (34) for silicone oil. The oil is density-matched with the reactor droplets such that a neutrally buoyant environment is created within the chamber (34). The oil within the chamber is continuously replenished by the oil separating the reactor droplets. This causes the droplets to assume a stable capillary-suspended spherical form upon entering the chamber (34). The spherical shape grows until large enough to span the gap between the ports, forming an axisym metric liquid bridge. The introduction of a second droplet from the second inlet port (32) causes the formation of an unstable funicular bridge that quickly ruptures from the, finer, second inlet port (32), and the droplets combine at the liquid bridge (30).

Abstract: Devices, systems, and methods for charging fluids are disclosed. The charging of fluids improves the mixing of fluids in microfluidic systems. The charging is performed by producing an ion field between an ionizing electrode and an opposed ground electrode. A fluid-containing vessel is positioned between the opposed electrodes and the ion field charges the fluid in the vessel.
