  \nAbstract  Double emulsions drops are small drops contained in larger
  drops. They can be used as picoliter-sized vessels to conduct chemical or
  biochemical reactions or to conduct high throughput screening assays. Key
  to a successful application of these drops is a good stability against co
 alescence and rupture. Previous studies have shown that the mechanical sta
 bility of double emulsion drops increases if their shell is reduced below 
 the µm scale. Unfortunately\, the fabrication of double emulsion drops wi
 th such thin shells at high throughputs is still challenging. Here\, we pr
 esent a new microfluidic device that reduces the thickness of double emuls
 ion shells to values as low as 250 nm. We demonstrate that the reduction o
 f the shell thickness of double emulsions improves their mechanical stabil
 ity and lowers their permeability. Moreover those drops can be used as tem
 plates for capsule production.\n\nBio Antoine Vian is studying his PhD in
  Prof. Esther Amstad’s group where he uses microfluidics as a tool to co
 ntrol encapsulation processes. He entered ESPCI  ParisTech (Ecole Superi
 eure de Physique et de Chimie Industrielle) after prep class in Stanislas 
 Paris. He  did part of his master thesis in Weitz lab in Harvard where h
 e had Esther as his supervisor. He started in September 2014 and he helped
  her mounting the lab. He also holds a MBA from college des ingenieurs in 
 Paris.
