Morphological Behavior for Micelle from Polystyrene-b-poly[2-(β- d -glucopyranosyloxy)ethyl acrylate] upon Changing the Copolymer Concentration

Multiple morphologies of molecular assemblies of polystyrene-b-poly[2-(β-d-glucopyranosyloxy)ethyl acrylate] (PSt-b-PGEA) were obtained by initially dissolving it in DMF and then adding water to the organic solution. With increasing the initial copolymer concentration (ICC) from 0.1 wt% to 2.0 wt% in DMF, the molecular assemblies of PSt77-b-PGEA6 were transformed from spheres, to rods, to vesicles, to tubules, and again to vesicles. Concanavalin (Con A) was used to characterize the surface properties of the resulting aggregates.
