An introduction to digital microfluidic concepts in chemistry using a macroscopic droplet generator

Abstract

<div><div><div><div><div><div><p>This activity introduces digital microfluidics and the usage of aqueous droplets as independent chemical microreactors for reaction kinetics studies. Students build their own droplet generator from common macroscopic glassware and connecting parts, to create trains of millimetric droplets in which a redox reaction takes place. The activity allows working on reaction kinetics, hydrodynamics at low Reynolds number and image analysis at a macroscopic scale.</p></div></div></div></div></div></div>
