A Microfluidic System for Controlling Reaction Networks in Time

Abstract

Millisecond mixing and transport with no dispersion are achieved by unsteady flows induced in droplets of about 60 pL that travel through winding microfluidic channels (top). Fluorescence can be used to monitor mixing (bottom) or measure reaction rates. In principle, arbitrarily complex reaction networks can be created by combining and splitting streams of such droplets.
