A delicate system, that is, in situ photoreduced silver metal nanoparticles (NPs) formed from a combination of Ag+ complexes with L- or D-cysteine, enables the introduction of chirality. This chirality is essentially programmed by a synergetic interplay between the CO2− and NH3+ groups on cysteine, rather than the formation of a chiral metal core (see figure).
