Effect of aging time and surface properties on the hydrophobicity and functionality of immunoglobulin G (IgG) antibody adsorbed on cellulosic films. Red, cellulose acetate film (CAF); blue, regenerated cellulose film (RCF). (A) Effect of IgG antibody aging on the relative size of agglutinates on CAF and RCF surfaces. Data were fitted with a one-phase decay, with R2 of 0.9778 (CAF) and 0.9965 (RCF). (B) Effect of IgG antibody aging on surface hydrophobicity on CAF and RCF. Data were fitted with Boltzmann function, and the R2 are 0.988 (CAF) and 0.937 (RCF).
