In this study; cotton fabric was successfully modified to have an antibacterial property through use of the sol-gel process. Dodecanethiol-capped silver nanoparticles; which have powerful antibacterial activity; were incorporated in silica sol. The starting materials were silver nitrate; tetraoctylammonium bromide; sodium borohydride; chloroform; 1-dodecanethiol; ethanol; tetraethylorthosilicate; and water. The cotton fabric was padded with dodecanethiol-capped silver nanoparticle-doped sol; dried at 60°C; and cured at 150°C. Scanning electron microscopy showed a uniform and continuous layer of doped sol on the fiber surface. The antibacterial effects of the treated cotton fabric against Escherichia coli were examined and found to be excellent. © 2006 Wiley Periodicals; Inc;
