Adsorption isotherms for human serum albumin (HSA, 66kDa) plotting the solution depletion D_i against initial solution concentration $W_{B_i}^o$ (mg/mL) for five different silanized glass-particle adsorbents exhibiting 113°-60° advancing buffer contact angles θ_a obtained using the solution-depletion method (see ref. [32] for details). The adsorbent capacity (D_i)^max and initial solution concentration at which the adsorbent was saturated by HSA ${\left(W_{B_i}^o\right)}^{\max }$ (see star annotations) decreased monotonically with adsorbent hydrophilicity at fixed total surface area (see Fig 12). Lines through the data are guides to the eye.
