Could nanotechnology save ancient books from crumbling?

Abstract:
Enter nanotechnology. Baglioni and his colleagues have a fix: An alcohol-based solution containing 100-nanometer particles that they spread on the pages. The nanoparticles, made of calcium hydroxide or magnesium hydroxide, stick to the cellulose fibers and begin to suck up the protons that hang around and make the paper acidic. Once the fibers are chemically stabilized, the books should last longer, Baglioni said, although it's hard to know what will happen in the long term: Scientists have a number of ways simulate the effects of aging, but no universally accepted way to predict the success of de-acidification.
