Sentences with phrase «silica nanoparticles»
Silica nanoparticles are tiny particles made of the mineral silica. Silica is a common material found in sand and rocks. These nanoparticles are so small that you would need a microscope to see them. They are used in various fields like medicine, electronics, and cosmetics because of their unique properties. Full definition
Scientists at the University of Florida Particle Engineering Research Center and personal products manufacturer Kimberly - Clark recently found an answer by coating silica nanoparticles with copper ions, a potent odor - fighting combination that could be used in powders and spritzes, mixed with cat litter, or embedded in products like garbage bags.
