Eric Drexler first described possible methods for creating nanometer scale devices in the mid-1980s [1]. Since then, various methods, including some not described by Drexler, have been attempted, with many of them finding success.rnA nanotube is a structure of atoms arranged to form a tube -similar to a roll of chicken wire. The carbon atoms are the intersection of the wires, and the wires are the bonds between the atoms.
