Abstract

Microfluidic devices and methods that utilize ion concentration polarization within water-in-oil nanoliter scale droplets for concentration enrichment, separation, and substitution of charges species are disclosed. Such devices and methods can be used for separation of multiple species by mobility of each species and for the alteration and manipulation of the droplet composition by ion exchange.
