“…The angle for minimum reflectivity is shifted by Δθ = 0.12°. While the points shown in Figure (curves a and b) correspond to the experimental data, the solid lines appearing in the curves corresponds to the Fresnel numerical fits . From these fits we estimate that the index of refraction of the monolayer is n = 1.53 and its thickness is 11.0 Å.…”

“…Thus, any perturbation in the dielectric properties of the metal−solution interface, i.e., as a result of the adsorption or binding of chemicals on the metal support, is expected to alter the SPR conditions. Indeed, SPR has been extensively used to characterize the formation of monolayers or thin films on metal supports. The binding of proteins and other biomaterials on metal surfaces was examined by SPR …”

Photostimulated association and dissociation of anti-dinitrophenyl antibody, anti-DNP-Ab, to and from a dinitrospiropyran photoisomerizable monolayer is probed by surface plasmon resonance (SPR). The anti-DNP-Ab binds to a dinitrospiropyran antigen monolayer, whereas the DNP-Ab dissociates from the protonated dinitromerocyanine monolayer. Reversible binding and dissociation of anti-DNP-Ab to and from the photoisomerizable monolayer was assayed by SPR spectroscopy. Analysis of the SPR data indicates that the average thickness of the antibody layer is ca. 70 Å which corresponds to a surface coverage of ca. 4.4 × 10-9 mol·cm-2.
