What does this research mean for the field?

The intrinsic three-dimensional morphological handedness of the metallic core in gold nanoparticles, rather than the chirality of surface ligands alone, dictates the sign and magnitude of spin-selective charge transport. Novelty: ClaimNovelty.NOVEL_FINDING. Consensus alignment: ConsensusAlignment.NEUTRAL.

What question did this study set out to answer?

Determine whether surface ligand chirality or the intrinsic three-dimensional morphology of the metallic core controls the sign and magnitude of chirality-induced spin selectivity.

Implication

Experimental study demonstrates that core morphology dictates spin-polarization sign in chiral gold nanoparticles, indicating that three-dimensional metallic structure governs spin transport.

Key Points

Determine whether surface ligand chirality or the intrinsic three-dimensional morphology of the metallic core controls the sign and magnitude of chirality-induced spin selectivity.
Synthesized trisoctahedral and petal-cube-like chiral gold nanoparticles using L-cysteine-directed seed-mediated growth at varying ligand concentrations.
Evaluated optical and spin-dependent transport properties via ensemble circular dichroism, single-particle circular differential scattering, electromagnetic simulations, and magnetic conductive-probe atomic force microscopy.
Trisoctahedral and petal-cube-like gold nanoparticles synthesized with the same L-cysteine enantiomer exhibited opposite circular dichroism handedness and opposite spin-polarization signs.
Intrinsically chiral gold nanoparticles produced spin polarization roughly one order of magnitude larger than achiral gold nanoparticles functionalized with L-cysteine.
