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)
....

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:
