The Study of Antibacterial Properties Nano-silver Colloid

摘要

Nanotechnology has become one of the most practical technologies, because of uniquephysical and chemical properties of nanomaterials.In this study, antibacterial effect of silver nanoparticles with average size 45nm on Escherichia coli strain wasinvestigated.Liquid and agar nutrient medium used for E.coli cultureand different antibiotics used for Disk diffusion technique to evaluate antibiotic resistance pattern of E.coli.Antibacterial effect of 1% and 3% of silver nanoparticles evaluated via discdiffusion test.Based on this study, nano-Ti02 has efficient antibacterial effect and can beused as an antibacterial agent for different purposes.
