Figure 2. — (a) Calculated effective interface potentials for the interaction between a keratin layer and a silicon wafer (type T and type N). The short-range constant was assumed as , resulting in maximal forces of . (b) Relative difference in vdW forces on type T and type N wafers as determined using equation (3.2). (c) Estimated pull-off forces for a β-keratin sphere of radius R = 150 nm on a Si/SiO₂ bilayer material with layer thickness d making use of equation (3.4). (Online version in colour.)
