Passive Mixing inside Microdroplets [PDF]

open access: yesMicromachines, 2018
Droplet-based micromixers are essential units in many microfluidic devices for widespread applications, such as diagnostics and synthesis. The mixers can be either passive or active. When compared to active methods, the passive mixer is widely used because it does not require extra energy input apart from the pump drive.
