a Schematic illustration showing the plane above the nanoparticle surface utilized for simulation under CPL irradiation and simulated electric field differences under LC and RC excitation for D-Au and L-AuPd, respectively. The color scale represents the magnitude of the field difference, with red indicating positive difference and blue indicating negative difference. b Adsorption energy for H2O2 homolytic dissociation on the Pd surface as a function of the electron level (σ). The adsorption configuration of reaction intermediates is also shown. The navy, red, and white balls represent Pd, O, and H atoms, respectively. Adsorption energy for the D-glucose oxidation on the (c) D-Au surface and (d) L-Au surface as a function of the hole level (σ). The adsorption configuration of reaction intermediates is also shown. The yellow, red, gray and white balls represent Au, O, C and H atoms, respectively. Isothermal Titration Calorimetry (ITC) data of the D-glu interaction with (e), (f) D-Au (Kd= 28.2 μM, N = 1 (Fix)) and (g), (h) L-Au (Kd= 60.9 μM, N = 1 (Fix)). Kd represents dissociation constant, and N represents binding stoichiometry. The experimental data are shown as solid squares, and the least squares’ best-fit curves derived from a simple one-site binding model (fixed) are shown as red lines. Insets are the side view of D-glu on Au (321) surface. The yellow, red, gray and white balls represent Au, O, C and H atoms, respectively. Source data are provided as a Source Data file.
