They're made from silica. Why not structures from cars like that?

Embedding nanoparticles in a material for instance, always.

Nanotechnology, nanoparticles, you hear a lot of worry about this.

This is soap that's made from silver nanoparticles, which have antibacterial properties.

Well, the surface of the spray coating is actually filled with nanoparticles that form a very rough and craggly surface.

In fact, sulfur reducing bacteria, as part of their synthesis, they will emit, as a byproduct, nanoparticles into the water.

But then right after that, they emit a protein that actually gathers and aggregates those nanoparticles so that they fall out of solution.

And it has billions of interstitial spaces, and those spaces, along with the nanoparticles, reach up and grab the air molecules, and cover the surface with air.

Loose nanoparticles. What is really interesting to me is that not many people have been asking, How can we consult nature about how to make nanotechnology safe?

New materials such as fused silica glass, ultra low expansion titanium silicate, and glass ceramic, to name a few, as well as application of advanced glass coating techniques, could improve dramatically the capability and reliability of remote sensing instruments.
