Antimicrobial effect of Sliver Nanoparticles Synthesized by Chemical Reduction on some Bacteria and Fungi

摘要

Background; Nanotechnology involves the tailoring of materials at atomic level to attain unique properties, which can be suitably manipulated for the. Most of the natural processes also take place in the nanometer scale regime. Aim; The purpose from this experiment was to describe antimicrobial effects of sliver nanoparticles on some bacteria and fungi. Method; The morphology and size of particles of nanoparticles were determined by scanning electron microscopy (SEM) and Visible absorption spectrophotometer. Results; The antimicrobial effect was studied using the well agar diffusion and broth dilution techniques. The MIC of sliver nanoparticles were 30 ppm for Candida albicans, Candida tropicalis and Candida Krusei. Compared to other strains (E. coli, Pseudomonas aureginosa, S. aureus) 100 ppm. The antimicrobial activity was observed against all tested microorganisms at different concentration of nano sliver. The Ag NPs causes growth delay for treated isolated with different concentration used in the experiment (increased concentration, increased growth inhibition). Conclusion; The study revealed that sliver nanoparticles can be further developed as an antimicrobial agent, hence high activity against microorganisms.
