In this study a simple and reproducible method was used to develop silver-embedded silica materials with antibacterial properties. Silica matrices were synthesized via a sol-gel route which allows one to easily tailor textural and chemical properties. Various characterization techniques, namely, FE-SEM, TEM, XRD, FTIR, TGA/DTGA, and nitrogen physisorption studies were employed to investigate and substantiate the final products. 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 results demonstrate that materials with more desirable properties and suitable for antibacterial applications can be obtained by this newly developed technique. |
