Chiral Gold Nanopropellers: Engineering Plasmonic Chirality for Enantioselective Recognition Through Stereoselective Binding (Advanced Optical Materials 1/2026)

Chiral Gold Nanopropellers The cover features chirally twisted gold “nanopropellers” functionalized with cysteine that couple plasmonic chirality with stereospecific molecular recognition, enabling enantioselective surface-enhanced Raman spectroscopy (SERS) of amino acids. Control experiments, density functional theory (DFT), and finite-difference time-domain (FDTD) simulations confirm a dual mechanism in which handed near-fields amplify selective adsorption, yielding highly sensitive and selective chiral light–matter interactions. More details can be found in the Research Article by Xiao You and co-workers (DOI: 10.1002/adom.202501589).
