Applications
Silver nanoparticles are widely recognized for their strong antimicrobial properties. They are used as antibacterial and disinfectant agents and are applied in certain pharmaceutical contexts, including some AIDS-related treatments. Incorporating small amounts of silver nanopowder (~0.1%) into various inorganic matrices makes these materials highly effective in eliminating pathogenic microorganisms such as Escherichia coli and Staphylococcus aureus. These disinfectant properties remain durable and stable across varying pH and oxidation conditions.
Silver nanoparticles also serve as efficient chemical catalysts, enhancing the speed and efficiency of reactions such as ethylene oxidation. They are important in biological and diagnostic studies, including gene-related research.
Beyond medical and scientific fields, silver nanoparticles are used in household and consumer products such as washing machines, refrigerators, air conditioners, toys, clothing, food containers, and detergents. Additionally, construction materials can gain antibacterial and corrosion-resistant characteristics through coatings enhanced with silver nanoparticles.
