Silver nanoparticles in hydrogels emerge as new antimicrobials


An Indian research group says it has developed a promising new antimicrobial additive based on silver nanoparticles (AgNPs). The first commercial application may be polymer-silver nanocomposite films for wound dressing applications.

"AgNPs combined with polymeric hydrogels offer a new class of materials that combine the antimicrobial properties of AgNPs with the human-tissue-like performance of hydrogels," said lead author Sunil Bajpai, a polymer science PhD at the Government Model Science College in Jabalpur, India.

Particles of silver that measure less than 100nm have been a major research focus in recent years because their antimicrobial effect is greatly enhanced due to their high ratio of surface area to volume. They also have unique optical, electrical, and thermal properties and are already used in photovoltaic systems and various sensors.
