Enantioselective detection of L- and D-cysteine shows notable spin polarization, indicating significant chiral recognition implications.
Spin‐resolved photoluminescence approach is employed for the enantioselective detection of L‐ and D‐cysteine using quantum dot‐functionalized ferromagnetic electrodes. The L‐cysteine‐functionalized system exhibited a spin polarization P s of 21.5% and a quenching efficiency (QE) of 35.6%, while the D‐cysteine system showed 9.2% P s and 21.0% QE. The detection limits are determined to be 1.86 nM for L‐cysteine and 20 nM for D‐cysteine. These results demonstrate the validation of the chiral‐induced spin selectivity effect and also establish a sensitive, spin‐based fluorescence platform for enantioselective biosensing of amino acids.
