Aspects of liposomes and micelles. A representation of the steric organization of a liposome (left) and a micelle (right). Liposomes have a lipidic bilayer (bottom) whereas micelles are constructed only by one lipid layer that has its apolar section turned inwards while its polar heads interact with the environment. As a result, the enclosed space in micelles is much more confined to that available in liposomes.
