Background

While many techniques exist to create multiple emulsions (droplets in droplets), they create large droplets that are limited in many ways. For example, multiple emulsion droplets are typically made one at a time and are accumulated at a very slow rate of about one milliliter per hour. Most techniques also require new equipment that prevents scaling down to the nanoscale. Furthermore, these techniques frequently produce unstable emulsions.Overcoming these challenges to create complex nanoscale particles would show great promise in fields such as pharmaceuticals, food, agriculture, and consumer products.
