微流体装置可以形成乳液，其中液滴具有复杂的受控结构;然而，挑战是液滴产生缓慢，通常每小时只有几毫升。在这里，我们提出了一种简单的技术来提高生产率。使用大型液滴制造机，我们以快速的体积速率产生大液滴;通过在分裂阵列中分裂这些液滴多次，我们创建所需小尺寸的液滴。与直接使用小液滴制造器形成小液滴相比，这种方法的优点在于可以以快得多的速率形成液滴。这可以应用于单乳液和多重乳液的生产。
Microfluidic devices can form emulsions in which the drops have an intricate, controlled structure; however, a challenge is that the droplets are produced slowly, typically only a few millilitres per hour. Here, we present a simple technique to increase the production rate. Using a large drop maker, we produce large drops at a fast volumetric rate; by splitting these drops several times in a splitting array, we create drops of the desired small size. The advantage of this over forming the small drops directly using a small drop maker is that the drops can be formed at much faster rates. This can be applied to the production of single and multiple emulsions.
