Self-assembly (also called Brownian assembly) is a term used to describe a spontaneous organization of individual pre-existing components into an ordered structure without human or supernatural invention. Self-assembly is generally considered a reversible process, tunable by varying a thermodynamical parameter such as density or temperature, and one that can be controlled through judicious design of the components. A self-assembled structure’s form is typically based on thermodynamic principles in which free energy is minimized. However, self-assembly is a fundamental principle which generates structural organization on different scales, from a molecule (random motion of molecules) to galaxies.
There are mainly two kinds of two main kinds of self-assembly; static self-assembly and dynamic self-assembly. Static self-assembly happens when it does dissipate energy and involve systems that are at global or local equilibrium. Dynamic self-assembly happens only if the system is dissipating energy
Self-assembly is used applications such as:
- Crystallization at all scales.
- Robotics and Manufacturing.
- Nanoscience and Technology
- Netted Systems
