Original sentence: Djokic and Burrell investigated silver oxide’s role, concluding, “An essential factor leading to an antimicrobial activity of metallic silver is a presence of Ag oxide(s) at the surface of this material.One important thing to note is while frequently described as being silver some are composed of a large percentage of silver oxide, this is due to the large ratio of surface to bulk silver molecules.Silver nanoparticles are generally held to be particles, sometimes crystalline in nature, of less than 100nm in size.Silver oxide has been used as an antimicrobial coating in the past, and the silver oxide component of the nanoparticles could play a significant role in their antimicrobial efficacy.The antimicrobial efficacy is inversely proportional to size, with smaller particles being more effective
Edited sentence: Samsung has created and marketed a material called Silver Nano, that includes silver nanoparticles on the surfaces of household appliances.Silver nanoparticles have an antimicrobial effect that is greater than that of ionic silver (ie silver nitrate).Silver nanoparticles have an antimicrobial effect that last longer than ionic silver.While frequently described as being 'silver' some are composed of a large percentage of silver oxide, this is due to the large ratio of surface to bulk silver molecules
