Metal-ligand interface effect in the chirality transfer from l- and d-glutathione to gold, silver and copper nanoparticles.

ABSTRACT: Glutathione (GSH) plays a pivotal role in numerous physiological and metabolic processes, including the defense of cells against free radicals and metal toxicity. This tripeptide has been combined with several metal nanoparticles to form a metal-organic interface with unique properties. Here, we implement a one-step, high-yield synthesis method to produce ultrasmall gold, silver, and copper nanoparticles in the intermediate size regime between size-selected nanoclusters and plasmonic nanoparticles to be functionalized with l- and d-glutathione, and study the chirality transfer evidenced by the emergent optical activity observed for each case. The distinctive interactions that take place at the metal-ligand interface for each metal are primarily accountable for establishing the properties o
