Positional diamondoid mechanosynthesis

A method for performing mechanosynthesis comprising:

• selecting a reactant or plurality of reactants from the group consisting of the carbon group and non-metal elements, excluding the noble gases;
• bonding a positionally controlled mechanosynthetic tool to a workpiece;
• further positionally controlling the movement of the bonded tooltip to cause a change in the molecular geometry or the electronic state of one or more atoms comprising the workpiece;
• wherein there is a barrier to undesired reactions sufficient to achieve a desired reliability of operation at a given temperature because the application of mechanical force is required to drive a desired chemical reaction.

A method for building a mechanosynthetic tool, the method comprising:

• arranging a first atom or plurality of atoms in an engineered atomically precise molecular structure;
• selecting a reactant or plurality of reactants from the group consisting of the carbon group and non-metal elements, excluding the noble gases;
• altering either or both the bonding pattern and the electronic state of said first atom or plurality of atoms during a site-specific mechanosynthetic chemical reaction with said reactant;
• and
• arranging a second atom or plurality of atoms affixed to said first atom or plurality of atoms in an engineered atomically precise molecular structure in which neither the bonding pattern nor the electronic state of said second atom or plurality of atoms is altered during said site-specific mechanosynthetic chemical reaction;
• wherein there is a barrier to undesired reactions sufficient to achieve a desired reliability of operation at a given temperature because the application of mechanical force is required to drive a desired chemical reaction, and any positionally controlled tips used in the method for building the mechanosynthetic tool are atomically imprecise.
