Abstract: Nanotechnology has the potential to affect the field of wood preervation through the creation of new and unique metal biocides with improved properties. This study evaluated leachability and efficacy of southern yellow pinewood treated with copper,zinc,or boronnano particles against mould fungi,decay fungi,and Eastern subterranean termites. Results showed that nano copper with and without surfactant,nanozinc,and nanozincplussilver with surfactant resisted leaching compared with metaloxide controls. Nearly all nanoboron and boric acid was released from the treated wood specimens during leaching.Mould fungi were moderately inhibited by nanozincoxide with surfactant,but the other nanometal preparations did not significantly inhibit mould fungi.Mass loss from Gloeophyllumtrabeumwas significantly inhibited by allcopper preparations,while Antrodiasp.was not inhibited by nanometal treatments. Nanometals imparted high resistance in southern yellow pine to the white-rot fungus, Trametesversicolor. Unleached specimens treated with nanoboronornanozincplussurfactant caused 100% and 31% mortality,respectively. All specimens treated with nanozincornanozincplussilver inhibited termite feeding, but the copper treatments were less effective against termites. Nanozinc possessed the most favorable properties:leach resistance,termite mortality,and inhibition of termite feeding and decay by the white-rot fungus.
