Estimating the term…
The present invention generally relates to emulsions, and more particularly, to multiple emulsions. In one aspect, multiple emulsions are formed by urging a fluid into a channel, e.g., by causing the fluid to enter the channel as a “jet.” Multiple fluids may flow through a channel collinearly before multiple emulsion droplets are formed. The fluidic channels may also, in certain embodiments, include varying degrees of hydrophilicity or hydrophobicity. In some cases, the average cross-sectional dimension may change, e.g., at an intersection. Unexpectedly, systems such as those described herein may be used to encapsulate fluids in single or multiple emulsions that are difficult or impossible to encapsulate using other techniques, such as fluids with low surface tension, viscous fluids, or viscoelastic fluids. Other aspects of the invention are generally directed to methods of making and using such systems, kits involving such systems, emulsions created using such systems, or the like.
