Specific tooltips are brought into contact with and bond to specific feedstock molecules distributed on a presentation surface, and then transfer said feedstock molecules to specific atomic sites on a workpiece using mechanosynthetic chemical reactions. Specific sites on a workpiece can be made chemically reactive, facilitating the transfer of specific groups to them. Repeated applications of molecular tools at different locations on a workpiece can build a desired atomically precise structure. | 04-09-2009 |
