Can a metal be made chiral? Evidence is provided for the induction of chirality in metals doped with chiral molecules (see figure). Gold and silver doped with L-glutathione or L-quinine or either D- or L-tryptophan show clear differences in the emission efficiency of the metal photoelectrons when irradiated with either clockwise or counter-clockwise circularly polarized UV light.
