This article focuses on strategies that have been implemented by the microfluidics community to overcome difficulties associated with microfluidic mixing. Diffusive mixing, a passive mixing strategy, was one of the first techniques introduces for mixing in a microfluidic channel. Passive diffusive mixing has evolved from a simple but inefficient technique into a highly efficient mixing process with improved performance and dramatically decreased mixing times. Passive diffusive mixing will continue to be the most frequently applied mixing approach in a microfluidic format due to its elegant simplicity.
