Though we don't know for sure, it seems that the most likely 'reaction' to nano-tech exposure would be similar to other toxins. It would require a
certain amount of exposure, and then toxic levels would build up.
Simply having incidental contact with a small amount of super-powdered quartz would not necessarily cause organ failure.
Now, it might be possible for an -injection- of a nano-tech engine, such as something that could insinuate itself into biological processes might be
able to cause massive damage to organs causing them to fail. The engine would also have to be self-reproducing to develop the sheer numbers of copies
which would quickly become toxic.
What I'm suggesting is that, sure, bio-toxic nanotech weaponized systems could be created. But not all nano-materials are bio-toxic in small
quantities by definition.
Clearly the technology is in its infancy, so I'm not sure one can definitively make an assessment, but so far this is what we're seeing.
(For analogous situation, check out this reference on nano-tubes being similarly toxic to asbestos fibers.
