Pressure-treated wood is great stuff, but the chemicals used to preserve it from decay can leach out, where they can be toxic to insects, fungi and other creatures.\u00a0Now, a team of Michigan Technological University scientists has used nanotechnology to keep the chemicals inside the wood where they belong. \u201cThis is a new method that uses nanoparticles to deliver preservatives into the lumber,\u201d said chemistry professor\u00a0Patricia Heiden.<\/a> \u201cIn our experiments, it reduced the leaching of biocides by 90 percent.\u201d The nanoparticles are tiny spheres of gelatin or chitosan chemically modified to surround the fungicide tebuconazole. No special handling is required, the wood is just pressure-treated in the usual way.<\/p>\n
