An article in the Philadelphia Inquirer ("The tiniest building blocks", by Faye Flam, 1 April 2002) presents a rather muddled view of recent research by David Luzzi and others at the University of Pennsylvania into novel carbon structures, including fullerene molecules inside nanotubes, which the article rather grandiosely describes as "a new form of matter". The article also makes a number of highly disparaging remarks about the prospects for advanced nanotechnology systems . . . as if carbon nanotube research were the end point, rather than a faltering first step. The article is accompanied by a short sidebar that gives an equally muddled presentation on the use of self-assembly to create some interesting nanotube arrays.
