Cross-talk between emulsion drops: how are hydrophilic reagents transported across oil phases?

- Summary

Abstract

We demonstrate that small aqueous drops form in surfactant-containing oils that are in contact with aqueous phases. These drops transport even large reagents across oil shells of double emulsions, resulting in cross-contamination. This can be reduced by using appropriate surfactants or by reducing the shell thickness below 1 μm.
