Self-assembly of gold nanoparticles into small clusters
Berlin, Germany (SPX) Aug 07, 2014
Researchers at HZB in co-operation with Humboldt-Universitat zu Berlin (HU, Berlin) have made an astonishing observation: they were investigating the formation of gold nanoparticles in a solvent and observed that the nanoparticles had not distributed themselves uniformly, but instead were self-assembled into small clusters. This was determined using Small-Angle X-ray Scattering (SAXS) at BESSY II. A thorough examination with an electron microscope (TEM) confirmed their result. "The research ... read more
