Fluidic conduits for highly efficient purification of target species in EWOD-driven droplet microfluidics†
Abstract
Due to the lack of continuous flows that would wash unwanted specifies and impurities off from a target location, droplet microfluidics commonly employs a long serial dilution process to purify target species. In this work, we achieve high-purity separation for the case of electrowetting-on-dielectric (EWOD) based droplet microfluidics by introducing a “fluidic conduit” between a sample droplet and a
