The micellization of diblock copolymers in a selective solvent for one of the blocks is a very useful method to produce well-defined nano-objects that may be useful for a variety of applications. Micelles from diblock copolymers are characterized by a rather simple structure consisting of a core formed by the insoluble blocks surrounded by a corona of the soluble blocks. Although spherical micelles are the most widely reported examples, other morphologies including rods, vesicles and other intricate morphologies have been described, depending on the chemical nature and of the composition of the diblock copolymers. Moreover, more complex structures than core-corona micelles have been obtained whenever ABC triblock copolymers are considered for micellization. In that respect, various multicompartment micelles have been recently obtained. Information on these micelles can be found in a recent review.
