Silver nanoparticle synthesis using strawberry tree leafMadrid, Spain (SPX) Jul 17, 2012 A team of researchers from Greece and Spain have managed to synthesize silver nanoparticles, which are of great interest thanks to their application in biotechnology, by using strawberry tree leaf extract. The new technology is ecological, simple, cheap and very fast. Strawberry tree leaf (Arbutus unedo) and silver nitrate (AgNO3). With just these two ingredients scientists can now produce silver nanoparticles, a material that is used in advanced technologies from compounds for distributing medici ... read more |
