BACKGROUND Bacterial resistance against the classic antibiotics is posing an increasing challenge for the prevention and treatment of infections in health care environments. The introduction of antimicrobial nanocoatings with active ingredients provides alternative measures for active killing of microorganisms, through a preventive hygiene approach. PURPOSE The purpose of this study was to in...

Nanosilver (10−9 m) refers to particles comprising 20–15,000 silver atoms, exhibiting high stability and specific surface area. At present, nanosilver has been used in agricultural cultivation production. This study examined the effects of on growth development rice root systems. Study results showed that fresh weight belowground organs length both increased significantly by 5% 25%, respectivel...
