| 摘要 |
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). |
