Concavity-enhanced chiral self-assembly of anisotropic nanoparticles toward strong chiroptical activity

BSA-induced chiral self-assembly GNDs

The biomolecule BSA was employed as a chiral additive to induce the twisted side-by-side self-assembly of cetyltrimethylammonium bromide (CTAB)-stabilized GNDs in solution to form chiral assemblies (Fig. 1a)….
