Chaotic micromixing in open wells using audio-frequency acoustic microstreaming
BioTechniques, 2009 Mixing fluids for biochemical assays is problematic when volumes are very small (on the order of the 10 µL typical of single drops), which has inspired the development of many micromixing devices.

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.

Optimization of Microfluidic Geometry for Extracellular Vesicle Capture Using an Automated Parallel Pattern Search. [PDF]
ProteomicsABSTRACT Microfluidic affinity‐based capture of extracellular vesicles (EVs) holds great promise for disease diagnostics and monitoring therapeutic EV production. However, optimizing microfluidic channel geometries for efficient EV capture remains understudied due to the effort required to experimentally test numerous designs.
