Re. carbon nanotube and graphene technologies, I’ve been impressed by the rate of progress. I say more in a recent post, <a href="http://metamodern.com/2009/11/12/carbon-nanotube-transistors-on-dna-origami/" rel="nofollow">“Carbon Nanotube Transistors through DNA Origami”</a>.

Which raises the possibility of extremely long lasting materials made of graphene. Slightly off topic, but still on the subject of graphene, I recently came across a couple of articles which to me seemed related: http://nextbigfuture.com/2009/11/self-asse...tubes-into.html An article on using DNA lattices to position CNs into precisely defined positions and this one http://www.nanowerk.com/news/newsid=13456.php An article on the ability to use current photolithography techniques to create graphene components for electronics. Reading the two together it seemed feasible that between the two techniques, a completely carbon based computer could be possible in the near future, and seeing your article here on graphene made me curious as to your opinion.
