Interfacial Phenomena (01c)

#581 - Biomolecules at Interfaces I (01C08)
This session welcomes contributions describing experiment and theory for a wide range of biomolecules (proteins, DNA, polysaccharides, etc.) and a broad range of interfaces, both liquid-solid and liquid-liquid. Relevant topics include: protein adsorption, biological forces and adhesion, biomembranes, transport of biomolecules across interfaces, changes in biomolecule conformation induced by interfaces, and interfacial engineering for applications such as biosensing, biomedical materials development, and bioseparations. Traditionally, this session has emphasized fundamentals over applications, but contributions from both sides are encouraged.
