Chemists have always been in the business of taking atoms and putting them together with other atoms with precisely defined connections.

Nanoengineering is learning how to make devices as small as 10 to 100 atoms in width. Much of the work is going on in the electronics industry, where there is great demand to pack more components onto computer chips.
