Applications:
Silver nanoparticles are well known for their antimicrobial properties. It can be used as an antibacterial and disinfectant, even in some cases
it finds uses in AIDS drugs. Addition of very small amounts of silver nanopowder (~0,1%) into different inorganic matrices makes those materials
effective for killing pathogenic microorganisms like Escherichia Coli, Staphylococcus Aureus, etc.This disinfectant properties are insensitive to
different pH or oxidation conditions and can be considered durable. In some cases it finds uses as a chemical catalyst as well. They can significantly
improve the speed and efficiency of various chemical reactions such as ethylene oxidation. Another important area that silver nanopaticles find usage
is the biological studies such as diagnostic works on genes. As well as medical-pharmaceutical and scientific applications, silver nanoparticles can be
used in household items as well. Manufacturers began to use silver nanopowders in products such as washing machines, refrigerators, air conditioners,
toys, clothing, food containers, detergents etc. Construction materials and buildings can contain antibacterial, corrosion resistant properties
by applying silver nanoparticle added paints on them.
