Abstract:
Metallic nanorods are welded together in a controllable fashion. A suspension of metallic nanorods coated with an anionic polymer is contracted with linking molecules each comprising a liquid crystal with at least two available carboxylic acid moieties. The nanoparticles to self-assemble into dimers. Irradiation of the dimers with femtosecond radiation forms a metallic junction between them and welds the dimers into fused dimers.
