Microfluidic mixing using PDMS-based microporous structures

Microfluidic mixing using PDMS-based microporous structures

We showed that efficient mixing of fluid flows at microscales can be achieved by a simple type of micromixers based on microporous structures. We used sugar particles as templates for fabricating the microporous structures. We quantitatively studied the relation between the mixing performance and th...
