Chaotic mixing in microdroplets [PDF]
Lab on a Chip, 2006 We describe a general methodology for introducing thorough chaotic mixing in microdroplets. The mixing properties of fluid flows in microdroplets are governed by their symmetries, which give rise to invariant surfaces serving as barriers to transport. Complete three-dimensional mixing by chaotic advection requires destruction of all flow invariants. To

Molecular Extraction and Release of an Ionic Liquid Microdroplet With Dynamic Tunability Under Optical Trapping. [PDF]
ChemphyschemWe produce a single microdroplet by inducing local phase separation of a temperature‐responsive ionic liquid aqueous solution under optical trapping conditions. As the droplet grows, molecules in the surrounding solution are extracted to the droplet. Upon droplet shrinkage, these molecules are released from the droplet. The molecular release process is
