A nano-manipulator with atomic resolution can position work pieces at sub Ångström distances.
Atomic resolution:
- is akin to printing resolution
- must not be confused with atomic precision which only require correct bond topology (=connectivity).
- makes direct mechanosynthetic fabrication of AP structures one H atom or moiety at a time possible.
- makes design and reasoning easier
- makes the creation of structures with higher performance and similar or higher efficiency (diffusion transport has free energy cost) than biological systems display possible (superlubricating interfaces).
Thermal expansion or bending through external forces can spoil atomic resolution in 3D space over great distances. This isn't a problem in nanofactories where relative distances between (sturdy) AP workpieces and (sturdy) AP tooltips are microscopic.
