This article is a stub. It needs to be expanded.

(wiki-TODO: discuss this)

High level physical effects that misleadingly may suggest infeasibility:

  • High wear in MEMS due to "stiction"
  • Focus on the for current day directly applicable material science (alloys)
  • Focus on the for material science interesting heavy metallic elements with intersting magnetic properties (f shells) – rare elements ...
  • Barely controllable diffusion: on surfaces, in grain boundaries, of dislocations
  • High difficulty to achieve very high levels of vacuum (UHV at best – nowhere near PPV)
  • Immense difficulties with SPM: getting and keeping tips sharp reliably, limits in imageable hight steps, speed limits, ...
  • Difficulties in designing artificial proteins for binding (not to speak of catalysis)
  • ....

Why is should be feasible despite all that

Low level physical effects (from first principles) that prove feasibility:

There is also high level evidence but this is weaker:

Both low and high level evidence:
