| Abstract: Q-switched Nd:YAG laser has been employed to prepare colloidal solutions of silver nanoparticles. SEM investigations as well as the surface Plasmon of UV-Vis spectra reveal formation of silver nanoparticles. Those nanoparticles were exhibited antibacterial activity on some bacteria which live in human body. It is found that higher concentration of silver nanoparticles of 50 µg/ml and small nanoparticles (less than 25 nm) would increase the inhibition zone around the implanted bacteria and reach 15 mm for Proteus. Remarkable increment of antibiotics when silver nanoparticles added to improve the antimicrobial effect against gram-negative and gram-positive bacteria. It is also found that the most sensitive bacteria for silver nanoparticles was Proteus and the minimum inhibition concentration of 15 µg/ml was obtained for Staphylococcus | ||
