Light beams can be used to “weld” a large number of nanoparticles together according to new experiments by researchers at the University of Cambridge in the UK and the Donostia International Physics Center in Spain. The technique could be used to self-assemble sophisticated nanostructures like chiral metamaterials from the bottom up for applications in molecular sensing and to make so-called cloaking devices…….
