Images of the STM made it also possible for the first time
to observe the helical structure of DNA covered by proteins
in a quasi-natural environment.

The simulation of the pushing process by the STM (left)
helped understand how the molecule (top view at right) specifically
designed for these experiments can "walk" on an
atomically flat copper surface.

Six STM images show how a ring of molecules was formed
by positioning randomly scattered molecules one by one on
a surface with an STM tip.

Scientists of IBM's Zurich Research Laboratory showed
that it is possible to move individual C60 molecules along
atomic steps of a copper surface and thus to form a molecular
abacus.
