Sweeter smelling socks and safer hospitals

Blasting silver nitrate solution can produce antibacterial silver nanoparticles without the need for a host of reagents, according to researchers in India. The study by Rani Pattabi and colleagues at Mangalore University, suggests that silver nanoparticles generated in this way are more effective than chemically produced particles in tests against resistant strains of Staphylococcus aureus, Streptococcus pneumonia, Escherichia coli and Pseudomonas aeruginosa, varieties of gram positive and gram negative microbes, some of which are untouched by conventional antibiotics. The research could assist in the production of bactericidal materials.
