Abstract

Background and Objectives:  Gold and silver nanoparticles have antibacterial and antimicrobial properties and microbes do not grow on their surfaces. These materials can be used in cosmetics, medical and textile industries in forms of antibacterial gel and antibacterial cloths. In the present work has been Al2O3 nanoparticles doped by Ag in vitro and production of these materials according to their antibacterials properties has biological and medical applications is enormous. 
Subjects and Methods:Al(NO3)3·9H2O, NH4HCO3, AgNO3, Deionized water, Ethanol.Production of Nanoparticles by precipitaton.
Results: In this experiment, alumina nanoparticles doped with silver is synthesized and for confirmation of results we have used XRD technique and Sherrer formula. Finally, it is found that alpha phase of nanoparticles has been formed.
Conclusions: Al2O3 doped with Ag composite activate by silver oxygen to produce active oxygen and beside SiO2 or TiO2 semiconductor acts as an electrochemicall cell. By oxidizing oxygen atom it produces oxygen ion and by hydrolysis of water,  produced. The produced ions are very strong antibiological agents.
