7. Silver nanoparticles/nanopowders application
 
A nanoparticle is defined according to nanotechnology as a small object between 1 and 100 nanometers that behaves like a whole unit. Silver in different forms has been widely used in medicine for curing disease and help promote wound healing since early times. A common form of silver that is used to treat infections is silver nitrate. This was formerly used as a prophylactic treatment of ophthalmia neonatorum in infants, but was discontinued because of the risk of blindness due to silver nitrate toxicity.
 
Silver nanoparticles have several characteristics that make it currently among the most widely used nanoparticle in science.  One highly useful characteristic is its antimicrobial property.  Silver in its pure form was  known, even to the by ancient Greeks, as a great material to keep microbes at bay.  If silver is transformed into a nanoparticle, this anti-microbial property is intensified, making it useful in effectively eliminating fungus, bacteria, and viruses.  As a natural material, silver is known to be safe to man and produce little to no allergic reactions when tested for curing various diseases.
