Abstract

Abstract : The electronic spin filtering capability of a single chiral helical peptide is measured. A ferromagnetic electrode source is employed to inject spin‐polarized electrons in an asymmetric single‐molecule junction bridging an α‐helical peptide sequence of known chirality. The conductance comparison between both isomers allows the direct determination of the polarization power of an individual chiral molecule.
