Abstract

Read online

Chirality of amino acids can be transferred to the high index plane of gold nanoparticles, resulting in chiral plasmonic nanoparticles called the 432 Helicoid series. Here, the authors present a 432 Helicoid IV and describe a systematic approach to modulate the chirality of single particles by controlling the kinetics.
