Hydrophobicity and hydrophilicity of biosurfaces

Hydrophobic interaction and hydrophilic repulsion occur in aqueous media and are caused by Lewis acid-base interactions of molecules, membranes or vesicles, with and among the surrounding water molecules. Recent scientific literature has been concerned with hydrophobicity/hydrophilicity of amino acids and proteins; protein adsorption and desorption (including influence of the secondary configuration of proteins, kinetics of protein adsorption and desorption, desorption and attenuation of adsorption of proteins, role of hydrophobic sites of proteins); hydrophilic repulsion and stabilization; aqueous partitioning (including coacervation and complex-coacervation); and phospholipids, membranes and vesicles (including inclusion of peptides into phospholipid layers, inclusion of polyethylene oxide into phospholipid layers, dissociation and lysis of phospholipid bilayers, removal of sterols from phospholipid monolayers, influence of plurivalent cations on charged and neutral phospholipid layers).
