Photopolymerization-Induced Polymersome Rupture.

Poly(butadiene)- b-poly(ethylene oxide) (PBut- b-PEO) giant polymersomes were prepared using an emulsion-centrifugation method. The impact of a fast decrease of the osmotic pressure inside the lumen of giant PBut- b-PEO vesicles was studied by confocal microscopy. This osmotic imbalance was created by performing the photoinduced polymerization of acrylamide inside these giant polymersomes, mimicking cell-like confinement.
