I am surprised to read this article about the production of CNT and Graphene in tonns and the increasing usagage of these materials. Alteast CNT is arguably carcinogenic so their use in that quantity is not good for environment.

Yes, there have been reports that graphene flakes should be handled carefully like carbon nanotubes have to be handled carefully during facbrication--like many other hazardous materials used in chip fabrication. However, once they are fixed in place on a chip, they appear to be safe. Also there has been some reports that claim carbon nanotubes are a biocompanible material that, when used carerfully, can boost neural functions!

We have been mining diatomacious earth here in the US for many years. Small particles can be easily inhaled into the lungs, providing a high surface area place for nasty things to happen. From what I've read, the carcinogenicity of CNT's are essentially similar..

super nano filters?

To protect against the inadvertant inhalation of these nano materials while in the manufacturing process is quite tricky as the filters required need to be of supernano size. Are such filters available?

You are right that filtration of airborne nanoparticles is a tricky process. A recent article explains ins and outs.

Perceptions are more powerful than reality. And there are so many contradictory research so it is nearly impossible to know the whole truth. I am just putting my opinions about the CNTs  and most of them are based on what i hear or read.
