'''Tooltip chemistry''' is the term for the special kind of chemistry that takes place when robotic means are used to bring molecular components [[atomic precision|accurately]] together such that a certain desired permanent chemical transformation is enforced and archived with very high probability. In short when [[mechanosynthesis]] is performed.
Usually covalent bonds are involved.

Typical processes are:

* picking molecules from pockets
* modifying molecular [[Moiety|moieties]] on tooltips 
* depositing molecular [[Moiety|moieties]] to workpieces

For [[diamondoid|carbon]] as building material extensive studies have been done [http://www.molecularassembler.com/Papers/MinToolset.pdf]
since this kind of tooltip chemistry was of central importance for showing the feasability of advanced productive [[atomic precision|AP]] nanosystems ([[technology level III]])

At the first step toward [[technology level III|advanced APM systems]] (the step towards [[technology level I]]) the involved tooltip chemistry is largely non covalent and untypical. It more resembles a conventional macroscopic assembly process. Here complementary surfaces can be used that stick together by VdW and ionic attraction forces. For the next step to [[technology level II]] tooltip chemistry is yet largely unclassified and unexplored.

['''Todo:''' add arrow diagram of the complete set of refresh cycles from the minimal toolset for positional diamond mechanosynthesis! - this is needed for e.g. mill design. Split recharging diagram from deposition diagram]

'''Beside for building of structures tooltip chemistry can be used for [[Chemomechanical converters|energy conversion]].'''
