(a) Potential of mean-force (PMF), (b) different contributions to PMF: the protein-surface attraction β U ps, the steric repulsion β U π V , and the electrostatic attraction β U Ψ q within the layer, (c) protein volume fraction and (d) polymer volume fraction as a function of position for three different stages during the protein adsorption at pH = 7.
