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

When going to larger sizes one faces:

  • much lower speeds – typically much below the speed of sound
  • much larger distances
  • => much much lower random part encounter rates

The encounter rate of small molecule sized parts at the nanoscale due to thermal motion is mindbogglingly high.
To get an intuitive feel about just how much macroscale is at a disadvantage see page: The speed of atoms

This obstacle can be hit when scaling termination control and site addressability in
technologies that use thermally driven self-assembly to raher large scales.
Like e.g. already the casein the higher selfassembly levels of structural DNA nanotechnology.
