用于将试剂注入液滴的现有方法利用集成到微流体芯片中的金属电极，这给制造过程增加了麻烦且容易出错的步骤。在这里，我们介绍了一种方法，使用注射液本身作为电极，通过利用溶解在溶液中的电解质。这消除了对金属电极的需要，并减少了制造时间和复杂性，同时还提供了对注入试剂体积的精确控制。
Existing methods for injecting reagents into drops utilize metal electrodes integrated into the microfluidic chip, adding cumber-some and error-prone steps to the fabrication process. Here, we introduce a method that uses the injection fluid itself as an electrode by exploiting dissolved electrolytes in the solution. This obviates the need for metal electrodes and reduces fabrication time and complexity while also affording precise control of the injected reagent volumes.
