Friday Random Ten: Functionalized Nanotubes Safe Edition

C&EN reported this week on a PNAS article (that I can't seem to access) dealing with the absorption of functionalized carbon nanotubes to mammallian tissues. It looks like they may, in fact, be safe for drug delivery engineering:

In the study, mice were intravenously administered water-soluble carbon nanotubes, either single-walled or multiwalled. Electron microscopy analysis revealed that both types of nanotubes are excreted intact in urine.
"This is the first time carbon nanotubes have been administered intravenously and fundamental pharmacokinetic parameters have been obtained," Kostarelos tells C&EN. "It is also the first description of carbon nanotubes circulating in the blood of live animals and the first report showing blood clearance and urine excretion of the nanotubes."

OK. On with the music!
