Unique biological performance of the silver nanoparticles prepared by using carboxymethyl chitosan and sunlight

In this paper, the study of the biological performance of the silver nanoparticles prepared by a method which had been reported by us was presented. The silver nanoparticles prepared by this method contain a minute amount of silver chloride. In this work, it was found that Escherichia coli bacteria was more sensitive to the silver nanoparticles containing more silver chloride and Staphylococcus aureus bacteria was more sensitive to the silver nanoparticles with the less silver chloride content. The antibacterial sponge which can be used as a dressing was successfully prepared by the original reaction of this novel method.
