Abstract:

The silver nanoparticles that have been studied in this research were produced by low cost chemical reduction method. X-ray diffraction was used for estimation of particle size of silver nanoparticles which were found to be 8 nm. The aim of this study was to determine the anti-microbial effects of silver nanoparticles synthesized by low cost chemical reduction method. The antibacterial activities were studied against gramnegative and gram-positive bacteria. The results showed that the small size silver nanoparticles had significant effects on bacteria. These small size nanoparticles rapidly penetrated inside the cell and stopped the growth of bacterial disease. Furthermore, the antifungal activity was studied by inspecting the effects against saprophytic fungi, which conformed that the silver nanoparticles were active against saprophytic fungi.
