Diversifying Nanoparticle Assemblies in Supramolecule Nanocomposites Via Cylindrical Confinement

Scientific Achievement

Fabrication of complex 3-D nanoparticle assemblies enabled a Au helical ribbon-like assembly with chiral plasmonic response several orders of magnitude higher than that of natural chiral materials.

Significance and Impact

Complex 3-D particle assembly beyond typical morphology defined by the phase diagram opens a viable path toward designer composites with access to targeted properties.
