The whole "lasts one year" thing intrigures me. What happens to it as time passes? Does it chip away over time? Does it weaken and gain imperfections or something? If that's the case, woud it really be a good idea to use this stuff, as they suggest, in an oven or on other surfaces that come in contact with food?

I wasn't able to read the whole article due to internet stupidity, but is this product going to be dispensed in spray cans? If so, what kind of inhalation threat does this pose?

If it sprays out like water then it probably won't have a fume. Though I'm guessing it either.

dissolves harmlessly into the air

or

melds into what ever it's sprayed on.

But my money's on it simply losing its protective properties and transparency.

Ah, nanochemistry. So much interesting stuff happens with it. I wish I took the lecture/lab when it was offered last year.

It'd be no more harmful than if you ate some sand. This is just Silicon Dioxide (sand, glass) on the nanoscale (where it can form different crystalline structures and has some different properties).

Also, yeah, Sith is dead-on about Van Der Waals. You come to know it well as a Chem major.

As Sith said, there's already some work been put into it. The main problem with creating true 'gecko feet', however, is that the nanostructures we produce are not the best self-cleaning. So, they loose efficiency and degrade with use as more particulates get caught in the nanostructures. They are preforming research on this problem, though.

Very insightful! Thanks!
