Researchers at Nanoscience middle of University of Jyväskylä in Finland have succeeded in producing short chains and rings of gold nanoparticles with unprecedented precision. They used a special kind of nanoparticles with a well-defined structure and linked them together with molecular bridges. These structures – being practically enormous molecules – allow extremely accurate studies of light–matter interaction in metallic nanostructures and plasmonics. This research was funded by the Academy of Finland.
