Review: The discovery of novel carbon-based nanoparticles was spurred
by the discovery of the buckminsterfullerene molecule in 1985. In this
review multi- and single-walled nanotubes (see Figure for a comical r
epresentation of nanotube connectors and tripods), carbon onions, and
carbon-encapsulated nanoparticles are covered. The interrelationships
between the various nanostructures the traditional forms of carbon are
also explored.
