Hi,

I have gone through your blog and I thought that it will really very helpful towards the issues.
Thanks for it….

I will tell you right now what the problem is: researchers and writers are confused and haven't grasped even an idea of the factors that asbestos researchers always talk about.

I have just spent 3 hours IN VAIN trying to figure out if I was exposed to danger when I spent 2 months working at a MWCNT factory where the MWCNTs were 20 microns in length but always SERPENTINE and never sharp and rod-like.

Some writers (very few) refer to a hard-to-find Brown et al 2007 study that they say showed that long and straight was dangerous while short and curly was OK.

BUT WHAT ABOUT LONG AND CURLY??? This shape is the predominant form in which MWCNTs come out of most ovens.

It is upsetting to see scientists not logically crossing their Ts and dotting their i's when making such discussions.

Why can't someone grasp this and deal with it? I want to know: does a long and curly nanotube, that has a tendency to aggregate into ropes, have any chance of even getting into the alveoli in the first place?

I really don't care to hear about 15 micron long straight nanotubes, which are obviously refined material, the powder of which would be too expensive to be allowed to float into the air and expose many workers.

I truly believe there have been a LOT of studies done, but of the Tuskeegee variety. I am a suffering victim of "nanotech" disease called Morgellons. I suggest anyone that has expertise in the field take a good long look at the photos in this report. See Jan Smith's Nanotech Nightmare – Morgellons Exposed site.

It is across the board, we all have the same manifestations. How does one grow polymer fibers and pick nano devices out of their skin? How did they get there in the first place? BIG BIG money is keeping this one sequestered…you can be sure.
Thanks for your efforts and as the previous poster acknowledged, "top notch" information.
Mm

For anyone interesting in reading more on this, the International Council on Nanotechnology (ICON) at Rice University has put together a useful backgrounder with comments from a variety of nanotechnology voices. It can be found at: http://icon.rice.edu/resources.cfm?doc_id=12299.
