Abstract

original image

Vesikel atmen CO2! Ein neuer Vesikeltyp, der sich aus Amidin-haltigen Diblockcopolymeren selbstorganisiert, „atmet“. Werden die Vesikel mit CO2 oder Ar behandelt, resultiert eine reversible Expansion und Kontraktion des Vesikelvolumens, ähnlich wie bei einer Luftblase (siehe Bild, PAD=Poly((N-amidino)dodecylacrylamid), PEO=Polyethylenoxid, Rh=hydrodynamischer Radius).
