Body armor of the future.

How are nanos in contact with human skin, eyes, and lungs? Is this wonder material the asbestos of the future? I’ve worked with fiberglass, and when cutting and sanding it, that fine dust works its way right into your dermis. Compared to fiberglass dust, nano dust must be much worse in its ability to work its way right into your cells.

I love materials breakthroughs, but......let’s ponder the future downside to our healt.

Asbestos was once considered a wonder material too.
