Fuck Yeah Double Emulsions !

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

Elegant and mesmerizing, these double emulsions, drops inside of drops, are generated with microfluidics for studying physics, biology, chemistry, robotics, and material science.

A ring of dark aqueous inner drops surrounds a larger aqueous inner drop. Their self-assembly occurs inside a large oil drop during their production in a microfluidic device. These drop formations are examples of Turing patterns and are ideal systems to study spontaneous symmetry breaking using Belousov-Zhabotinsky chemical reactions inside the smaller drops arranged in a one dimensional loop.
