And because they are cheaper, easier to apply and more environmentally friendly than substances currently in use, nanotechnology-based coatings could replace many of today's industrial paints and coatings.

The nano coatings, "liquid solids" composed of extremely tiny particles, possess unique characteristics -- like extreme flexibility, easy adhesion and resistance to corrosion and microbial growth -- that could profoundly change the manufacturing process.

Sally Ramsey, co-founder and chief chemist of Ecology Coatings, began exploring the costs and potential environmental benefits of nano coatings in 2003. She used nano-sized particles of mineral oxides to create waterproof coatings for paper at half the cost of synthetic paper. Derivative materials could be used to produce waterproof cardboard boxes, or integrated into building materials such as drywall to prevent mold from growing if it becomes wet, Ramsey said.

I'm imagining paintings that are living eco-systems of thriving, self-repairing nao-particles. The painting rebuilds itself every ten years like Ise shrine.
