Carbon nanotubes show promise for high-speed genetic sequencing

by on Jan.04, 2010, under Articles, Science

A new method for DNA sequencing in which a single-stranded ribbon of DNA is threaded through a carbon nanotube could be carried out thousands of times faster than existing methods at a fraction of the cost, if perfected, Arizona State University scientists say.

Carbon nanotubes show promise for high-speed genetic sequencing (PHYSORG)

Yay for the Carbon Nanotube!

WOOO! Carbon Nanotubes!!!

Using Nanotubes in Computer Chips (PHYSORG)

Yes my friends. You just read correctly. Not only will Carbon Nanotubes cause and cure lung cancer, but they’ll be making faster processors for us too! Its the ducktape of the future!!! (If ducktap was actually used to make computers that is)

CARBON NANOTUBES!

by on Apr.28, 2009, under Articles, Science

I know friends. It has been awhile. But once again I’ve found mention of Carbon Nanotubes!

Israel Institute of Technology researchers used a network of 10 sets of chemically modified carbon nanotubes to create a multicomponent sensor capable of discriminating between a healthy breath and one characteristic of lung cancer patients. Using 10 different organic coatings, the investigators created field-effect transistors comprising random networks of each of the different coated nanotubes, and the resulting array produces a characteristic change in electrical output when exposed to volatile nonpolar organic substances.

Actually a repeat of some news we saw earlier but still! They live!
