Many biological processes, such as regulation, catalysis, and complex formation, depend on the capacity of biopolymers to interact with apolar groups, i.e., their surface or “effective” hydrophobicity (1 ). The determination of surface hydrophobicity is therefore important for understanding the mechanism of interaction of a biopolymer with its ligands. The determination of surface hydrophobicity is also important for designing a method for the purification or the concentration of biopolymers, especially proteins.
