  • Title: Enhancing the plasmonic circular dichroism by entrapping chiral molecules at the core-shell interface of rod-shaped Au@Ag nanocrystals.
    Author: Hou S, Yan J, Hu Z, Wu X.
    Journal: Chem Commun (Camb); 2016 Feb 04; 52(10):2059-62. PubMed ID: 26687977.
    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.
