Droplet merging is an important part of droplet manipulation approaches. Droplet merging methods with expansions inside channels can merge droplets in pairs through simple structures. However, they have a low success rate of merging under unstable fluidic conditions since the one-to-one pairing strategy is sensitive to fluctuation. This study presents a one-to-a-cluster pairing strategy to improve the success rate of merging under fluctuation. The one-to-a-cluster method was suitable for digital analysis and droplet MDA was performed in merged droplets successfully.
液滴合并是液滴操控方法的重要组成部分。通道内带有扩张结构的液滴合并方法可通过简单结构成对合并液滴。然而,由于一对一配对策略对波动敏感,在不稳定的流体条件下它们的合并成功率较低。本研究提出了一种一对多簇配对策略,以提高波动条件下的合并成功率。一对多簇方法适用于数字分析,并且在合并后的液滴中成功进行了液滴多重置换扩增(MDA)。
