K-channel operation in PMMA for droplet splitting and magnetic bead concentration. (a) K-channel device design. (b) Flow of droplets in the main channel before and after splitting using a K-channel (c) Droplet immediately after splitting at the K-channel in the presence of applied magnetic field and zoomed image of split droplets with magnetic concentration of beads in the main channel and an empty droplet in the K-channel. (d) Droplet splitting at the K-channel in the absence of applied magnetic field and zoomed image showing no magnetic concentration: both droplets contain magnetic beads.
