Abstract
In this study a simple and reproduciblemethodwas used to develop silver-doped silica powder with antibacterial
properties. Silicamatriceswere synthesized via a sol–gel route which allows one to easily tailor textural and chemical
properties. A wide range of silica-materials/products was obtained via the present route. These are: pure silver
nanoparticles (Ag0), silver in ionic state (Ag+), AgCl nanoparticles, and the mixture of Ag0 and AgCl. The efficacy of
these products were tested against Escherichia coli and the results demonstrate thatmaterials that are suitable for
antibacterial applications were obtained by this newly developed technique while utilizing sodium silicate, which
is relatively inexpensive, as a silica precursor. This may significantly boost the industrial production of the inexpensive
silver-doped silica products for various applications. A project on other innovative industrial applications of
our products is in progress.
