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. http://phys.org/news261219067.html Nanotechnology Wed, 11 Jul 2012 09:51:17 EST news261219067 Food waste is a growing problem in many parts of the world, but discarded fruit peel, in the case of pomegranates, could be put to good use in the burgeoning field of nanotechnology according to research published in the International Journal of Nanoparticles. http://phys.org/news259320003.html Nanotechnology Tue, 19 Jun 2012 10:23:42 EST news259320003 Researchers in applied physics have cleared an important hurdle in the development of advanced materials, called metamaterials, that bend light in unusual ways. http://phys.org/news250426284.html Nanotechnology Thu, 08 Mar 2012 10:51:58 EST news250426284 Chemists at the University of Helsinki (Finland) have managed to manufacture new polymer-stabilised silver nanoparticles. The result is significant because the antimicrobial characteristics of silver are used in textiles, floor coatings and paints even though the impact on health of silver nanoparticles are not entirely known. Finnish researchers now think that exposure to silver can be reduced by chemically binding the nanoparticles to polymers. The research results will soon be published in a leading journal in the field, Colloid and Polymer Science. http://phys.org/news186226113.html Nanotechnology Wed, 24 Feb 2010 09:40:01 EST news186226113 Scientists in India are reporting successful laboratory tests of a new and potentially safer alternative to silver-based gels applied to the skin of burn patients to treat infections. With names like silver sulfadiazine and silver nitrate, these germ-fighters save lives and speed healing. The researchers describe gel composed of silver nanoparticles — each 1/50,000th the width of a human hair — that appears more effective than these traditional gels. Their study is scheduled for the Aug. 3 issue of ACS' Molecular Pharmaceutics. http://phys.org/news167477979.html Nanotechnology Wed, 22 Jul 2009 10:40:25 EST news167477979
