Silver nanoparticles have demonstrated efficient inhibitory activities against human immunodeficiency virus (HIV) and hepatitis B virus (HBV). However, the effects of silver nanoparticles against H1N1 influenza A virus remain unexplored. In this study, the interaction of silver nanoparticles with H1N1 influenza A virus was investigated. Silver nanoparticles with mean particle diameters of 10nm ...

Nanoparticles (NPs) of noble metals, namely gold and silver, remain promising anticancer agents capable of enhancing current surgery- and chemotherapeutic-based approaches in cancer treatment. Bimetallic AgAu composition can be used as a more effective agent due to the synergetic effect. Among the physicochemical parameters affecting gold and silver nanoparticle biological activity, a primary c...

Stable silver nanoparticles were successfully synthesized by chemical reduction of silver nitrate in ionic liquids 1Ethyl-3-methylimidazolium tetrafluoroborate [Emim] BF4 and 1Ethyl-3-methylimidazolium hexafluorophosphate [Emim] PF6 at room temperature. The characterization of the silver nanoparticles such as their size and shape was performed by X-ray Diffraction (XRD) and Scanning Electron Mi...
