Abstract
Rhombic dodecahedral gold nanoparticles (GNPs) are found to have inherent chirality and can be used as colorimetric probes for naked-eye recognition of histidine enantiomers. Our findings are helpful for developing new GNP-based chiral sensing systems through tuning of nanoparticle morphology.
