Thermally driven assembly is also called called self assembly or brownian assembly (seldom)
(TODO: Add minimal definition)
- Today thermally driven assembly is already extensively used (e.g. structural DNA nanotechnology) this will continue onward into the early stages of the development of atomically precise manufacturing (APM).
- In the early and the later stages of APM development: brownian mechanosynthesis could be an intermediate step to advanced APM systems.
- In the later and the final stages of APM development: self assisted assembly will come to intensive use.
Beside the actual function of the building block (structural element / machine element) completely unguided thermally driven assembly requires the building blocks to be have a unambiguous unique puzzle piece shape that completely determines its target position. (everything that can stick will stick)
- Brownian assembly is generally slower then advanced directed assembly like mechanosynthesis. (numbers needed)
- The ambient temperature dictates diffusion speed.
- Lower dimensionality that is diffusion on a surface instead of a volume or on a line instead of a surface speeds up the process.
- Dividing one long diffusion path to several shorter irreversible diffusion transport stretches speeds up the process.
Possible sub-classifications
- iterative self-assembly
- one-pot self-assemby (necessarily requiring a larger size of an orthogonal set of interfaces)
- self-assembly of floppy foldamer chains at the first selfassembly level
- self-assembly of stiff pre-self-assembled tiles at the second selfassembly level
(wiki-TODO: what are the overlaps and differences)
(wiki-TODO: what are advantages and limitations)

- Thermally driven assembly is a powerful for bootstrapping in the incremental path towards advanced APM. It can help the introduction of total positional control
- In thermally driven assembly diffusion transport brings the parts to their final destination.
- In the process of self folding the parts are already connected (assembled) on a common flexible backbone but there is further thermally driven folding happening. This may be counted to thermally driven assembly but is often not.
- Brownian technology path
- Kinetic traps
