Chaos and disorder in microfluidics

Dynamics obviously plays an important role in microfluidics: how long does it take for a biochemical reaction to develop, how long does it take for a microdroplet to form... More specifically, chaotic dynamics plays an important role in the domain of micromixing. Devices based on chaotic mixing, designed to accelerate mixing, are now currently used in the laboratories. To celebrate the memory of Jerry, I will show a few examples where chaos and disorder, in the way he liked to think about, are exploited to develop certain functionalities in microfluidic devices.
