Abstract
Multiple properties of plasmonic assemblies are determined by their geometrical organization. This patent focuses on the formation of Janus structure of the asymmetric assembly structure of the gold nanorods and gold nanoparticles. Chiral structure of gold nanorods and gold nanoparticles can be obtained through the characterization of optical spectra of the Janus structure. And it opens the door for the explanation of the mechanism of the chirality, plays a strong guiding role in the negative refractive material above and has good application prospects.
