"We are using nano quantities of the nanoparticles."

It's known that nanoparticles under certain --quite ordinary-- circumstances can move from the skin surface to layers underneath and into to the bloodstream. These particles may be 'cleared' from the body or they may lodge in various areas (lungs? brain?) and it is NOT known what the results of these particles hanging around the body will be.

Some studies have found that smaller particles are cleared faster than larger ones and so are safer, but others suggest that once inside the body, nanoparticles travel through the blood, lodge in the lungs and brain, and accumulate over time, with effects that are still poorly understood.

The entire country is an experiment for bioengineered food stuff. Evidently women will be main the subjects of the nanotech industry.
