Nanotech Glass Beads

According to Physorg.com, a "liquid glass" was invented in Turkey that utilizes nanotechnology.
The liquid glass spray (technically termed “SiO2 ultra-thin layering”) consists of almost pure silicon dioxide (silica, the normal compound in glass) extracted from quartz sand. Water or ethanol is added, depending on the type of surface to be coated. There are no additives, and the nano-scale glass coating bonds to the surface because of the quantum forces involved. According to the manufacturers, liquid glass has a long-lasting antibacterial effect because microbes landing on the surface cannot divide or replicate easily.

If this technology works as stated in the blurb, then the inventor has lovered the viscosity of the glass suspension by making the beads on the nanoscale.  This coating allows surfaces to be cleaned with hot water and has widespread applications.
