Silver effective on all kinds of bacteria

Silver nanoparticles effective at killing all kinds of bacteria
 

Writing in the International Journal of Nanoparticles, Rani Pattabi and colleagues at Mangalore University, explain how blasting silver nitrate solution with an electron beam can generate nanoparticles that are more effective at killing all kinds of bacteria, including gram-negative species that are not harmed by conventional antibacterial agents.

Bacterial resistance to conventional antibiotics is threatening human health the world over. Medicinal chemists are desperately trying to develop new compounds that can kill strains such as MRSA (methicillin, or multiple-resistant Staphylococcus aureus) and E. coli O157. Frontline defenses, such as environmentally benign and cost-effective antibacterial compounds could prevent such infective agents spreading through contact with computer keyboard, phones and other devices.

Silver has been known to have antibacterial properties since ancient times. A modern technological twist means it has come to the fore for a wide range of applications because of the emergence of resistance to antibacterial gels. As such a new industry involving the production of bacteriostatic agents, including silver nanoparticles, has emerged.
