A novel enantioselective surface plasmon resonance (SPR) sensor based on a self‐assembled monolayer of C 60 fullerene as the chiral selector is proposed. A binding assay, apparent affinity constant, and apparent dissociation binding constant were used to analyze and study the enantioselectivity of C 60 fullerene‐glutathione film for L‐histidine, which was chosen as the model analyte. The apparent affinity constant for the complex formed by L‐histidine with C 60 fullerene‐glutathione film was 5.2 x 10 9 M ‐1 . The proposed SPR sensor can be used for the assay of L‐histidine in the 10 ‐10 – 10 ‐7 mol/L concentration range. Chirality 26:129–131, 2014. © 2014 Wiley Periodicals, Inc.
