Abstract

We report the enhancement of plasmonic circular dichroism (PCD) in cysteine-modified Au nanorods via Ag coating. The entrapment of cysteine at the Au–Ag interface effectively amplifies the local electromagnetic field and leads to strong enhancement of the PCD response. Ag coating on spherical nanoparticles modified with cysteine does not generate obvious PCD signals.
