چکیده:

Nanotechnology is a most promising field for generating new applications in different industries.At nanoscale, silver exhibits remarkably unusual physical, chemical and biological properties. In this work we synthesized nanosilver coated on MgO powder and investigated the antimicrobial properties. The nanosilver composite was characterized with TEM, XRD, and atomic absorption. This substance is introduced as an antimicrobial agent in different industries, like agricultural, textile, polymer, packaging, ceramic, painting, etc. The antibacterial, antifungal effect of the products is derived from nanosilver particles which are adhered to the products. Nanosilver composite showed antimicrobial activities (microorganism reduction) against S. Aureus, E. Coli, P. Aeruginosa, because of the presence of the silver nanoparticles
