GLOBULAR-PROTEINS AT SOLID-LIQUID INTERFACES

Seven years have passed since one of us (W.N.) published the last comprehensive review on the mechanism of globular protein adsorption to solid/water interfaces. Since that time, annual contributions to the field have steadily increased and substantial progress has been made in a number of important areas. This review takes a fresh look at the driving force for protein adsorption by combining recent advances with key results from the past. The analysis indicates that four effects, namely structural rearrangements in the protein molecule, dehydration of (parts of) the sorbent surface, redistribution of charged groups in the interfacial layer, and protein surface polarity usually make the primary contributions to the overall adsorption behavior.
