Two teams working independently of each other have developed very similar methods for creating silver nanoparticles that appear impervious to rust. One of the teams was from the U.S. and published their results in the journal Nature. The other team was from China and published their results in the journal Nature Communications. Both teams were looking for a way to create silver nanoparticles that could be used as a replacement for the more expensive gold nanoparticles (used extensively in biomedical applications). Silver is more abundant and costs less but its sensitivity to oxidation makes it unstable, and thus unsuitable for most of the applications that gold nanoparticles are used for. To use silver as a basis for such nanoparticles the research teams had to find a way to cause them to be impervious to oxidation, and that’s just what both have achieved. Both teams wound up with nanoparticles that were made up of exactly 44 silver atoms. Likewise both teams used a similar technique to create the nanoparticles—mixing silver nitrates with reagents in ethanol and water. The difference between the two techniques developed by the two teams was in the sulfur bearing molecules used. In either case, both resulted in the formation of a solid
