01A07 Thermophysical Properties of Biological Systems
OverviewThe focus of this session is the study of complex processes in biological systems. Contributions from theoreticians, simulators, and experimentalists are welcome. Suggested topics include protein-protein interactions, concentration and crowding effects on biomolecular folding and stability, misfolding and aggregation events, interactions of proteins with interfaces, and self-assembly of biological molecules.
