AB - \&nbsp;Enantioselectivity in gold clusters is investigated by studying the adsorption\&nbsp;of a chiral amino acid (cysteine) on a chiral Au<sub>55</sub> cluster using density\&nbsp;functional calculations. The highest adsorption energies were found when the\&nbsp;amino and thiolate functional groups of cysteine are bonded to the lowest\&nbsp;coordinated edges of the chiral cluster. Enantiospecific adsorption is\&nbsp;primarily obtained from the different bond location and strength, at the\&nbsp;cluster edge, of the carboxyl groups forming the left- and right-handed\&nbsp;enantiomers. These results provide theoretical support to convey\&nbsp;enantioselectivity in asymmetric nanocatalysts using chiral gold clusters.
