Photopolymerization-Induced Polymersome Rupture [PDF]

Langmuir, 2019
Poly(butadiene)- b-poly(ethylene oxide) (PBut2.5- b-PEO1.3) 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
