FITC-LDL adsorption/desorption kinetics onto the hydrophobic C18 self-assembled monolayer region of the C18-silica gradient surface (θadv = 104°, fractional surface coverage of C18 groups, Θ/Θmax(C18) = 0.90) in the case of (a) co-adsorption with HSA, and (b) adsorption onto pre-adsorbed HSA. The dashed line indicates the flux of the FITC-LDL molecules to the surface calculated using Eq. 2
