Chiral Nanoparticles
In article number 2208299, Bing Ni, Sara Bals, Luis M. Liz‐Marzán, and co‐workers show how plasmonic optical activity in chiral nanoparticles can be tuned and optimized through the chiral morphological details. Twisted gold nanorods evolve through removal of mirror symmetry during dissymmetric seeded growth. Both experimental and theoretical analysis indicates that the underlying...
A robust and reproducible methodology to prepare stable inorganic nanoparticles with chiral morphology may hold the key to the practical utilization of these materials. An optimized chiral growth method to prepare fourfold twisted gold nanorods is described herein, where the amino acid cysteine is used as a dissymmetry inducer. Four tilted ridges are found to develop on the surface of single‐crystal...
