How are nanos in contact with human skin, eyes, and lungs? Is this wonder material the asbestos of the future? I’ve worked with fiberglass, and when cutting and sanding it, that fine dust works its way right into your dermis. Compared to fiberglass dust, nano dust must be much worse in its ability to work its way right into your cells.

I love materials breakthroughs, but......let’s ponder the future downside to our healt.

Asbestos was once considered a wonder material too.

carbon nanotubes

New nanotube findings by Stanford researchers give boost to potential biomedical applications

Circulation and long-term fate of functionalized, biocompatible single-walled carbon nanotubes in mice probed by Raman spectroscopy

The usual suspects are on the case, but I don't see how it is any more toxic than carbon or graphite, IMHO.
