Carbon Nanotubes: Now in fluorescent form

Fluorescent Nanotubes Enhance Mouse Imaging [Kurzweil AI]

So in the past we’ve learned that Carbon Nanotubes can be used to deliver drugs into the body quickly, or possibly even a targeted fashion. Now we can paint them fluorescent and inject them into the body and be able to track and image their progress with greater depth an accuracy than standard biocompatible dyes.

This means we can both deliver drugs and watch them get delivered in real-time. An amazing step in medicine.

Carbon-Nanotube Memory that Really
PhysOrg.com Jan. 26, 2009
Helsinki University of Technology
researchers have created a
carbon-nanotube based information
storage comparable in speed to
memory commonly used in memory cards
and USB flash drives. The memory
scheme has a write-erase time of 100
nanoseconds, which is about 100,000
times faster than previously
reported carbon-nanotube memory, and

Cheaper Fuel Cells
Technology Review Feb. 5, 2009
University of Dayton researchers
have shown that arrays of vertically
grown carbon nanotubes could be used
as the catalyst in fuel cells.
(Science) The carbon nanotubes,
which are doped with nitrogen, would
be much cheaper and longer lasting
than the expensive platinum
catalysts used now, with four times
higher current densities….

Okay peoples. That is my backlog of Carbon Nanotube news. So things will be slower now as the sudden explosion of discoveries seems to have tampered off to about once a week, rather than once a day. But as you can see, Carbon Nanotubes will be a savior and our destruction! All shall love and despair!
