Positional assembly
From apm
Positional assembly:
- is the complement to all forms of Self assembly
- does not need thermal motion to work such as most forms of self assembly (except Selfassembly without thermal motion)
- does need to sufficiently control thermal motion to prevent placement errors
- does not require the parts that are supposed to be assembled to encode their target position into their structure.
Thus added parts can be smaller (molecule fragment moieties or sometimes single atoms in the limit)
Thus stiffer (better) materials can be assembled - can be combined with self assembly.
Like e.g. in the site activation method and in tether assisted self assembly.
