Vesicles breathe CO 2 ! A new type of vesicle that self‐assembles from amidine‐containing diblock copolymer displays “breathing” features. Treating the vesicles with CO 2 or Ar can reversibly tune the expansion and contraction of the vesicular volume, as if a bubble is breathing (see picture, PAD=poly(( N ‐amidino)dodecyl acrylamide), PEO=poly(ethylene oxide), R h =hydrodynamic radius).
