The
nano-abacus is a nano-sized
abacus developed by IBM scientists. Stable
rows made up of ten molecules
act as the railings of the abacus. The beads are made up of fullerene and are pushed around by the tip of a
scanning tunneling
microscope. The nano-abacus
has the potential to be used in a variety of nanotechnological inventions
such as the nano-computer.
