We report the preparation of antibubbles
by microfluidic methods.
More specifically, we demonstrate a two-step approach, wherein a monodisperse
water-in-oil-in-water (W/O/W) emulsion of core–shell construction
is first generated via microfluidics and freeze-dried thereafter to
yield, upon subsequent reconstitution, an aqueous dispersion of antibubbles.
Stable antibubbles are attained by stabilization of the air–water
interfaces through a combination of adsorbed particles and polymeric
surfactant. The antibubbles strongly resemble the double emulsion
templates from which they were formed. When triggered to release,
antibubbles show complete release of their cores within about 100
ms.
