Pressure-treated wood is great stuff, but the chemicals used to preserve it from decay can leach out, where they can be toxic to bugs, fungi and other hapless creatures that have the bad luck to be in the neighborhood. Now, a team of Michigan Technological University scientists has used nanotechnology to keep the chemicals inside the wood where they belong.

The initial tests show that the nanoparticle-treated wood is just as resistant to rot and insects as conventionally treated lumber. The researchers are now testing the wood in the warm, wet weather of Hawaii.
