Nanotubes ‘as deadly as asbestos’ - Hardware - iTnews Australia

The researchers found that mice exposed to long, straight carbon nanotubes developed conditions that precede mesothelioma, which can take as long as 40 years to develop in humans.

Kenneth Donaldson, a professor at the University of Edinburgh, who was part of the research team, said that the effects of the nanotube exposure are virtually identical to those of asbestos.

You make structures the right size to diddle organics on a sub-organelle level, and it’s a wakeup call to learn it does exactly that. Good thing we haven’t be releasing nanostructured stuff into the environment for years already. Oh, wait.
