Silver (Ag) Nanopowder/Nanoparticles
Purity: 99.95%, Size: 18 nm, w/ ~0.25% PVP
Silver has long been recognized for its antimicrobial performance, and the high surface area of nanopowder enhances this effect. Silver nanopowders are versatile materials with broad application potential due to their electrical, optical, and biological properties. The PVP coating provides additional benefits by improving nanoparticle stability, reducing aggregation, and enhancing dispersibility in various solvents and matrices.
As Nano Chicago, we supply Silver Nanopowder in high quantities and multiple types to meet diverse application needs.

Applications of Silver Nanoparticles
Silver nanoparticles are widely known for their antimicrobial properties. They are used as antibacterial and disinfectant agents, and in some cases find use in pharmaceutical applications, including AIDS-related treatments. Adding very small amounts of silver nanopowder (~0.1%) to various inorganic matrices makes the materials effective at eliminating pathogenic microorganisms such as Escherichia coli and Staphylococcus aureus. These disinfecting properties are stable across varying pH and oxidative conditions.
Silver nanoparticles can also be used as chemical catalysts, significantly improving the efficiency and reaction rates of processes such as ethylene oxidation. They play important roles in biological studies, including diagnostic and gene-related research.
Beyond medical and scientific applications, silver nanoparticles are integrated into everyday household products, including washing machines, refrigerators, air conditioners, toys, clothing, food containers, and detergents. Construction materials can also benefit from antibacterial and corrosion-resistant characteristics through the application of silver nanoparticle–enhanced coatings.
