All‐Aqueous Emulsions: Generation of High‐Order All‐Aqueous Emulsion Drops by Osmosis‐Driven Phase Separation (Small 39/2018)

In article number 1802107, Ho Cheung Shum and co-workers demonstrate an approach to produce high-order, up to quadruple, all-aqueous emulsion drops, which are initiated by osmosis-induced phase separation from non-equilibrium aqueous two-phase systems on a glass-based microfluidic platform. The complexity of the generated all-aqueous emulsion drops is well predicted in a phase diagram, providing a strategy to fabricate all-aqueous emulsions with a tunable high-order structure.
