Abstract

Introduction: In the current research, the effectiveness of silver's NANO- PARTICLES anti- microbial activity on the pathogenic and resistant positive- gram and negativegram bacteria in the hospital infections have been studied. In this study, the primary density of bacteria was constant and only NANO- PARTICLES and items of studied bacteria were variable.Materials & methods: At first, this study uses the available chemical reagents and conditions only apply controlling optimum conditions, nanoparticles with a size of about 20-35 nm were synthesized by chemical precipitation method. Using MACRO DILUTION METHOD the different densities of silver NANO- PARTICLES and Zinc NANO- PARTICLES (medium+Nano- particle) were prepared as: 0.01 percent, 0.1 percent, 0.5 percent, 1 percent and 1.5 percent. Then density of 1.5 cell/ml was prepared for Staphylococcus aureus; Pseudomonas aeruginosa the containers which included treatment medium (bacterium+Nanoparticle) and control medium have been placed in INCUBATOR SHAKER with 250 cycle in minute and 37oC for 24h. after passing this time, light density 600 nm ware length was used for measuring bacteria density, then OD in treatment and+control and – control were determined. NANO- PARTICLES dilutions were used in bacteria medium for calibrating spectrophotometer as a blank solution.. These results are statistically significant. (P-value<0.01).Findings: Statistical analysis about Zn; Ag NANO- PARTICLES showed that in 0.5 percent density; NANO- PARTICLES were BACTERICIDE and they could eliminate 100% of Staphylococcus aureus; Pseudomonas aeruginosa; and in 0.01 percent density for all two bacteria, these NANO- PARTICLES were BACTERIOSTATIC.Discussion & Conclusion: in the laboratorial tests of Nano-Materials, contact with them, bacteria will be killed. The obtained results for NANO- PARTICLES' antibacteria property showed that there is a direct relationship between NANO- PARTICLES density and the amount of bacteriums elimination.
