(Related update): More From Nanotechnology Land

Related update: "Trojan Horse" nanotechnology?  Yep, and it holds the potential to address one of the worst forms of brain cancer known to medicine.  Here's an excerpt of this exciting new development from an article at
A "Trojan horse" treatment for an aggressive form of brain cancer, which involves using tiny nanoparticles of gold to kill tumour cells, has been successfully tested by scientists.

The ground-breaking technique could eventually be used to treat multiforme, which is the most common and aggressive brain tumour in adults, and notoriously difficult to treat. Many sufferers die within a few months of diagnosis, and just six in every 100 patients with the condition are alive after five years.
It's an interesting article with fascinating detail of the science and studies behind this new application of nanotechnology. [ht:]

Original post (7/5/14):  I'll let this selection from a fascinating article at MIT Technology Review do the talking:
For more than a decade, engineers have been fretting that they are running out of tricks for continuing to shrink silicon transistors. Intel’s latest chips have transistors with features as small as 14 nanometers, but it is unclear how the industry can keep scaling down silicon transistors much further or what might replace them.
A project at IBM is now aiming to have transistors built using carbon nanotubes ready to take over from silicon transistors soon after 2020. According to the semiconductor industry’s roadmap, transistors at that point must have features as small as five nanometers to keep up with the continuous miniaturization of computer chips. “That’s where silicon scaling runs out of steam, and there really is nothing else,” says Wilfried Haensch, who leads the company’s nanotube project at the company’s T.J. Watson research center in Yorktown Heights, New York. Nanotubes are the only technology that looks capable of keeping the advance of computer power from slowing down, by offering a practical way to make both smaller and faster transistors, he says.
In 1998, researchers at IBM made one of the first working carbon nanotube transistors. And now, after more than a decade of research, IBM is the first major company to commit to getting the technology ready for commercialization.
This, obviously, could be huge for IBM as well as for us, the consumer...another great example of the power of the profit motive!  [ht:]
