Nanothin SiO2-coated nanosilver

Silver nanoparticles (nanosilver) have superior optical (e.g. plasmonic) properties that make them attractive for biomedical applications. One hurdle up to now has been their toxicity. Researchers from ETH Zurich, however, have now found a solution by flame aerosol synthesis and subsequent in-situ coating nanosilver with nanothin silica films. Link to Press article in ETH Life
