The potential for using nano-copper particles for wood protection was investigated using mini-agar slant and wood block tests with Gloeophyllum trabeum or Trametes versicolor. Nano-copper was more effective against G. trabeum than T. versicolor, although neither of these fungi would be considered copper tolerant. Nano-copper solutions were stable over a 17 week storage period, but precipitated when subjected to a vacuum or when wood was added to the solution. The results suggest that nano-copper has potential as a wood protectant, but much more research will be required to understand the properties of this material.
