Phase diagram of nanoscale particles derived from aqueous hydration of PEO-b-PCL copolymers. Morphologies were determined qualitatively from cryogenic transmission electron microscopic studies of the self-assembled structures formed from thin film rehydration of 50:1 molar ratios of copolymer:Nile Red followed by extrusion through a 400 nm porosity membrane (S = spherical micelles, V = vesicle, P = precipitate; for systems exhibiting mixed morphologies, the major component is noted first).
