The thoroughly revised second edition of this book examines the role of polar interfacial and noncovalent interactions among biological and nonbiological macromolecules as well as biopolymers, particles, surfaces, cells, and both polar and apolar polymers. It emcompasses Lifshitz—van der Waals and electrical double layer interactions, as well as Lewis acid—base interactions between colloidal entities in polar liquids such as water.

This edition presents new material on the interplay between macroscopic-scale repulsions and microscopic-scale attractions in protein adsorption; revises interfacial tensions between polar organic liquids and water; examines the kinetics and energetics of protein adsorption onto metal oxide surfaces; discusses some lesser-known properties of liquid water, such as cluster formation and the hydrophobicity of the water—air interface; and more.

From the Preface: “...[A]s a consequence of an unusual development occurring shortly after the appearance in print of the first edition of this book, many changes had to be made in all those chapters with a heavy dependence on, and even in those with a more modest involvement in, the interfacial tension between condensed-phase compounds or materials and water...or in the closely related interfacial free energy of interaction between molecules, particles, or surfaces immersed in water...To explain these changes, a chapter (XIII) was added, devoted to `Interfacial Tension Determination'...”

Target Audience: Physical, colloid, and surface chemists; bio- and immuno-chemists; chemical engineers; microbiologists; and upper-level students in these disciplines.
