Emulsions stabilized with organic solid particles

► Biocompatible and biodegradable o/w emulsions stabilized by block copolymer micelles are investigated. ► Emulsions show excellent stability; the droplet size is controlled by the micelles-to-oil ratio. ► Fairly concentrated aqueous suspension of block copolymer micelles was prepared by a modified nanoprecipitation method. ► Adsorbed micelles reorganize at the oil/water interface because of the liquid state of the micellar core.
