  • Patent number: 10316873
    Abstract: The present invention generally relates to multiple emulsions, and to methods and apparatuses for making multiple emulsions. A multiple emulsion generally describes larger droplets that contain one or more smaller droplets therein. The larger droplets may be suspended in a third fluid in some cases. These can be useful for encapsulating species such as pharmaceutical agents, cells, chemicals, or the like. In some cases, one or more of the droplets can change form, for instance, to become solidified to form a microcapsule, a liposome, a polymerosome, or a colloidosome. Multiple emulsions can be formed in one step in certain embodiments, with generally precise repeatability, and can be tailored to include one, two, three, or more inner droplets within a single outer droplet (which droplets may all be nested in some cases).

  • Patent number: 8915259
    Abstract: The specification generally discloses systems and methods for mixing and delivering fluids in microfluidic systems. The fluids can contain, in some embodiments reagents that can participate in one or more chemical or biological reactions. Some embodiments relate to systems and methods employing one or more vent valves to controllably flow and/or mix portions of fluid within the microfluidic system. Advantageously, fluid control such as a sequence of fluid flow and/or a change in flow rate, can be achieved by opening and closing one or more vent valves and by applying a single source of fluid flow (e.g., a vacuum) operated at a substantially constant pressure. This can simplify the operation and use of the device by an intended user.
