Detailed explanation-1: -Self-assembly is the process of association of individual units of a material into highly arranged/ordered structures/patterns. It imparts unique properties to both inorganic and organic structures, so generated, via non-covalent interactions.
Detailed explanation-2: -Examples of self-assembly include protein folding, the formation of liposomes, and the alignment of liquid crystals.
Detailed explanation-3: -Self-assembly is the process in which a system’s components-be it molecules, polymers, colloids, or macroscopic particles-organize into ordered and/or functional structures or patterns as a consequence of specific, local interactions among the components themselves, without external direction.
Detailed explanation-4: -Self-assembly is the spontaneous association of an ensemble of molecules into one or more supramolecular structures, driven by multiple noncovalent interactions. These interactions include hydrogen bonding, electrostatic association, van der Waals forces, and are often mediated by the hydrophobic effect.
