Still, it's pretty damn small for a micromanipulator as they come
these days. What is more interesting is positioning precision -- STM
tips are very macroscopic, yet resolve down to few pm resolution, thus
making them clearly nanomanipulators.
One of the nano top down bootstrap schemes proposes using a
progressively smaller sequence of micromanipulators, each instance
used to build a smaller instance.
