			== Why not keep adding small parts to big parts? ==

			One can not just keep small fast diffusing parts to increasingly bigger (and non moving) products as <br>
			the addressing space on the surface gets too big eventually. <br>
			At last not with additional tricks as one way around the diffusion slowdown blockade. <br>

'''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. <br>
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 <br>
technologies that use [[thermally driven self-assembly]] to raher large scales. <br>
Like e.g. already the casein the higher [[selfassembly level]]s of [[structural DNA nanotechnology]].
