New Nanotechnology Application For Making Lumber Safe

lumberMichigan Technological University has reached to a new technology that would keep the chemicals-that preserve lumber used in buildings- in the lumbers instead of leaking in the ground gradually and harming the environment. The new technology is using fungicide within nanoparticles using gelatin or chitosan from the shellfish.

The nanoparticles are tiny spheres of gelatin or chitosan (a material found in the shells of shrimp and other shellfish) chemically modified to surround the fungicide tebuconazole. The little spheres require no special handling.

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.


The research is funded by the US Environmental Protection Agency. Also contributing to the project are chemistry PhD student Xiaochu Ding and, from the School of Forest Research and Environmental Science, Research Engineer/Scientist II Dana Richter, Senior Research Engineer/Scientist Glenn Larkin, Assistant Research Scientist Erik Keranen and Professor Peter Laks.
