Self-assembly The generation of a well-defined supermolecule from a given set of components, under appropriate conditions. The process involves three stages recognition between the components appropriate orientation of the components to allow growth of the structure termination of the growth to give a finite supramolecular species. The term also applies to the formation of supramolecular assemblies from their components.

Type IV collagen subtype [ctl(IV)]2Q 2(IV) from bovine lens capsule forms a fine meshwork structure containing many branches with about 20 nm between the branching points. There are three types of supramolecular assembly of type IV collagen molecules dimer formation (with six polypeptide chains) at the C-terminal NCI domain, the association of four molecules (12 chains) in a 30 nm tetramer formation at the N-terminal 7S domain, and lateral interaction at the collagenous domain (Figure 5(a)). ° ...

Morphologically diverse supramolecular assemblies have been formed from long-chain chiral aldonamides [370-378]. Typical compounds include 28 30. Formation of 200- and 300-A-diameter rods and helical rope-like structures in aqueous n-octyl- and n-dodecyl-D-gluconamide (D-28-8 and D-28-12) gpls has been recognized for some time [379]. In a subsequent work, helical double-... 

Self-assembly may occur with self-recognition, mixtures of components yielding defined superstructures without interference or crossover (see Section 9.5). A special case is self-resolution which results in the formation of homochiral supramolecular entities from racemic components (see Sections 9.4.2, 9.4.4 and 9.7).
