Introduction to the chemical and adhesive properties of macromolecules at interfaces. The fundamental physico-chemical forces that govern adsorption of macromolecules at interfaces and inter-particle adhesion will be discussed. Topics such as surface tension, self-assembly, adsorption of polymers and biomolecules, and bacterial cell adhesion will be discussed with emphasis on environmental applications. Identical to WES 572. (Offered even academic years only).
