Chirality resolution via series controlling angular momentum-LSPR component in multi-illumination environment.

Highly efficient chirality resolution method and widely adaptive chirality sensor of ZnO nanorods (ZnONRs) decorated with multiple kinds of noble metal nanoparticles (NMNPs) by optically modulating angular momentum of electrons excitation are introduced. The enantiomers of glutamine functionalized different layers of NMNPs decorated ZnONRs can be easily recognized by modulating angular momentum of electron excitation controlled by the 405 nm, 532 nm, and 635 nm laser irradiations from the split currents in J-V curve. The improving sensitivity of multilayer NMNPs component is investigated, which exhibits the maximum spin polarization of L -glutamine functionalized one to four layer is 27.52 % under 532 nm, 27.81 % under 635 nm, and 26.53 % under 405 nm laser, showing over 1000 % enhancement compared to the one of bare ZnONRs. Above all, this sequence NMNPs component provide the variable selectivity to chirality resolution dependent on illumination environment, which takes few mins to do the purification of a specific amino acid by the novel transmittance measurement. • Chirality sensing via angular momentum controlling electrochemical system. • Multi-illumination application for chirality sensing and separation. • Imitation of energy transfer mechanism of chlorophyll.
