A supposed submicroscopic particle that formed part of a biological organism
A theoretical aggregation of molecules constituting a structural particle of protoplasm, capable of increase or diminution without change in chemical nature.
a colloidal aggregate, in a simple geometric form, of a specific number of amphipathic molecules which forms at a well-defined concentration, called the critical micelle concentration
an electrically charged particle built up from polymeric molecules or ions and occurring in certain colloidal electrolytic solutions like soaps and detergents
A micelle () or micella () (plural micelles or micellae, respectively) is an aggregate (or supramolecular assembly) of surfactant molecules dispersed in a liquid, forming a colloidal suspension (also known as associated colloidal system). A typical micelle in water forms an aggregate with the hydrophilic regions in contact with surrounding solvent, sequestering the hydrophobic single-tail regions in the micelle centre.
