Silver Nanoparticle Applications

- Mar 24, 2017-

Silver nanoparticles are one of the most commonly utilized nanomaterials due to their 

anti-microbial properties, high electrical conductivity, and optical properties.


Silver nanopaticles are widely incorporated into wound dressings, and are used as an 

antiseptic and disinfectant in medical applications and in consumer goods. Silver nanoparticles 

have a high surface area per unit mass and release a continuous level of silver ions into their 

environment. The silver ions are bioactive and have broad spectrum antimicrobial properties against

a wide range of bacteria. By controlling the size, shape, surface and agglomeration state of the 

nanoparticles, specific silver ion release profiles can be developed for a given application.


Incorporation of silver particles into plastics, composites, and adhesives increases the electrical

 conductivity of the material. Silver pastes and epoxies are widely utilized in the electronics 

industries. Silver nanoparticle based inks are used to print flexible electronics and have the 

advantage that the melting point of the small silver nanoparticles in the ink is reduced by 

hundreds of degrees compared to bulk silver. When scintered, these silver nanoparticle based inks 

have excellent conductivity.
