K-channel operation in PMMA for reagent injection into the droplet. (a) K-channel device design. (b) Flow of droplet in the main channel before K-channel injection. (c) Flow of droplet across the K-channel in the presence of applied electric field and zoomed image showing disruption of boundary and exchange of fluid between the aqueous phases of the K-channel and the droplet due to the applied electric field. (d) Flow of droplet in the main channel after K-channel injection. (e) Flow of droplet across the K-channel in the absence of applied electric field and zoomed image showing no fluid exchange between the K-channel and the passing droplet. WE: working electrode; RE: reference electrode.
