"WebWe show that changing surface polarity has two profound effects. First, the amount adsorbed increases as the surfaces become more apolar. Further, the proteins become less stable as their adsorbed amount increased because they gain a large number of interprotein and protein-surface interactions.

Protein Adsorption - an overview ScienceDirect Topics

Polymers are of great importance when considering protein adsorption in the biomedical arena. Polymers are composed of one or more types of "mers" bound together repeatedly, typically by directional covalent bonds. As the chain grows by the addition of mers, the chemical and physical properties of the material are dictated by the molecular structure of the monomer. By carefully s… WebDespite the fact that the displacement of water from the surface of a hydrophilic material represents a large energy barrier to adsorption by proteins, the processes of charge …
