Proceedings of the National Academy of Sciences, 2006 The ability to mix liquids in microchannel networks is fundamentally important in the design of nearly every miniaturized chemical and biochemical analysis system. Here, we show that enhanced micromixing can be achieved in topologically simple and easily fabricated planar 2D microchannels by simply introducing curvature and changes in width in a ...

An example of a chaotic micromixer: the cross-channel micromixer [PDF]
Comptes Rendus Physique, 2004 In this article dedicated to micromixing, we concentrate here on a particular micromixer – the ‘cross-channel micromixer’. This mixer exploits an oscillatory perturbation to induce chaotic trajectories, favoring mixing. We present here theory, numerical simulations and experiments performed on this system.

Toward the Next Generation of Passive Micromixers: A Novel 3-D Design Approach
Micromachines, 2021 Passive micromixers are miniaturized instruments that are used to mix fluids in microfluidic systems. In microchannels, combination of laminar flows and small diffusion constants of mixing liquids produce a difficult mixing environment. In particular, in
