Good article.

My only suggestion is to keep your eyes and ears open and watch out for generalizations.

I have been working on some "nano-products" and these are manufactured at the wafer level - sort of like normal semiconductor fabrication. So the nano-widgets are fixed to what for all intents and purposes could be a mirror. You cannot inhale them.

Now - don't get me wrong - there is nothing environmentally friendly about semiconductor fabrication either. We use so many solvents and acids (like HF) it would make your head spin. But these nano-products on the wafer level are not airborne or water borne.

I was glad that the article cited specific examples where nano-tubes etc. were shown to be harmful. The fact is that the nano-robots etc. are pretty far off. Carbon nano-tubes represent a fairly active area of research right now.

The point of the article is a good one. Time will tell in terms of what comes out of all of this.

Thanks for the link,
