Next generation nanotechnology computer memory made of graphene

(Nanowerk Spotlight) Carbon comes in many different forms, from the graphite found in pencils to the world's most expensive diamonds. In 1980, we knew of only three basic forms of carbon, namely diamond, graphite, and amorphous carbon. Then, fullerenes and carbon nanotubes were discovered and more recently there has been a lot of buzz about graphene. Discovered only in 2004, graphene is a flat one-atom thick sheet of carbon. Existing forms of carbon basically consist of sheets of graphene, either bonded on top of each other to form a solid material like graphite, rolled up into carbon nanotubes (think of a single-walled carbon nanotube as a graphene cylinder), or folded into soccer ball shaped fullerenes.

Nanotubes & Memory

University researchers are trying to develop a nanodevice for data storage by using carbon nanotubes, which are made from rolled graphite sheets just one carbon atom thick

Nanotubes Deemed Different From Carbon

Sensing confusion among the nanotech industry, the Environmental Protection Agency has clarified its position on carbon nanotubes, saying they are chemically distinct from graphite and other forms of carbon. The move serves as a reminder that carbon nanotubes are considered new substances under the Toxic Substances Control Act (TSCA).

Seeing Nanotubes Targeting Tumors In Vivo

Carbon nanotubes have significant potential for delivering both imaging and therapeutic agents to tumors, but there is still a need to better quantify how well these rolled-up sheets of graphite can target tumors. Now, thanks to the development of a microscope capable of measuring Raman spectroscopic signals from living mice, researchers have a noninvasive tool to study where carbon nanotubes travel once they are injected into the blood stream.
