Summary

The authors present a versatile method to spatially pattern the surface properties of microfluidic devices using flow confinement. This technique allows surface patterning with micron-scale resolution, and to demonstrate its effectiveness, they use it to pattern wettability to form Water/Oil/Water and Oil/Water/Oil double emulsions.
