MOESM2 of High-throughput magnetic particle washing in nanoliter droplets using serial injection and splitting

Additional file 2: Video S1. High-speed video of modified device for washing of superparamagnetic microparticles. In order to prevent magnetic microparticle transfer into the injection channel, the channel diameter was decreased and was oriented at a ~ 45° angle with respect to the input droplet train channel. Droplet generation frequency is 50 Hz, magnetic microparticle size is ~ 1 µm.
