Physics in Drops

"It's like catching the fish that swallowed the queen's ring." Herzog by Saul Bellow.


Revolutionizing drops inside of drops one drop at a time. This blog is dedicated to the physics of microfluidics and double emulsions.

Controlled Release. Double emulsions, drops inside of drops, are useful as carriers of drugs and other macromolecules.  The mechanical properties of the shells, such as their elasticity, permeability and selectivity,  are tunable using different material compositions during their microfluidic production. Here we show a microcapsule with a bio-compatible wax shell composed of different triglycerides. As the shell is heated, the wax shell melts and expands releasing cargo containing different aqueous drops as seen in the gif above. (Gif and emulsion credit: L. L. A. Adams)
