Figure 3
Raw X-ray reflectivity data (circles) and diffuse scan (squares) of the aqueous-lysozyme-solution–silicon interface measured at pH 7. The inset shows the logarithm of the reflectivity normalized by the Fresnel reflectivity. The solid curve shows a refinement of the data assuming a 28 Å-thick lysozyme layer on the silicon surface which is equivalent to the formation of a protein monolayer. |
