Eco-friendly synthesis and antibacterial activity of silver nanoparticles reduced by nano-wood materials

Original Paper


Hydrothermal treatment of nano-structured wood, prepared by precision grinding, with cationic silver was found to give silver nanoparticles (Ag NPs) of 2–40-nm size range embedded in the wood tissue. The size and distribution of Ag NPs depended strongly on the starting silver ion concentration and reaction temperature. Higher temperature tended to give larger size and wider distribution. The obtained Ag NPs were characterized using various methods, including high-resolution transmission electron microscopy, UV–visible spectroscopy, and X-ray diffraction. The antibacterial effect of the product against Escherichia coli was evaluated by static and dynamic culture experiments, revealing that the Ag NPs-loaded nano-wood materials have great promise as antimicrobial agents against E. coli.
