IUPAC definition
Micelle: Particle of colloidal dimensions that exists in equilibrium with the
molecules or ions in solution from which it is formed.
Micelle (polymers): Organized auto-assembly formed in a liquid and
composed of amphiphilic macromolecules, in general amphiphilic di-
or tri-block copolymers made of solvophilic and solvophobic blocks.
