Sentences with phrase «metallic nanoparticles»

"Metallic nanoparticles" are very tiny particles made of metal, like gold or silver. They are so small that they cannot be seen with the naked eye and require special tools to observe them. These particles have unique properties due to their size, which make them useful in various applications such as electronics, medical treatments, and environmental protection. Full definition
