Nanotechnology, risks?

[sanctus]

Today I participated on an easter walk (I guess that's how you translate it) against war and general rearmament. There was a woman with a kind of flag telling between other things (like stop atomictechnolgy) "stop nanotecnology".

 

I was very surprised at this and so I asked her why?

First she seemed to make (or actually made?) confusion between nanoparticles and nanotechnology. She said things like that the weapons made with "enriched" uranium where not only bad for the radioactivity, but also because there are nanometer sized uranium particles created which do harm not only for their radioactivity...I told her that this has nothing to with nanotecnology.

She then replied that she had been at some scientific conference where a scientist also said that nanotechnolgy is very risky. While discussing I suggested that maybe during the production via nanotechnology of an object, maybe some heavy metal nanoparticles are liberated and as nanotechnolgy deals with not so common materials this might cause not common consequences...can this be true? Or can there be another reason to see something dangerous in nanotechnology?

I still think it to be harmless...

Nanotechnology Now - Current Uses

 

I'd say she's misinformed. Or perhaps she has a bit of the "Terminator 2" mentality. :)

 

Or perhaps it is a T2 kind of thing:

Just looking at this, as I've posted elsewhere...regarding nanotechnology.
