Key molecules in biological systems are polymers: proteins, polysaccharides and the nucleic acids. Their long chain behaviour is a crucial contributing factor to their function in living systems. The fundamental motif of cells - membranes that separate space into multicompartments - has an analogy with polymeric amphiphiles, their slow dynamics allowing access to both kinetic insights and tougher membranes. There is increasing dialogue between the different communities of polymer scientists and biologists/clinicians, reflecting the growing awareness that only by bringing together interdisciplinary ideas will fast progress be made. The meeting will aim to focus on two main strands: the physical chemistry of macromolecules as common ground between biology and polymer science; and the problems associated with biocompatibility and biodegradability of polymers, particularly with regard to their role as therapeutic delivery vehicles. Themes of the meeting will include: Cells and membranes Self assembly processes Signalling pathways Molecular motors Dynamics Drug delivery Tissue scaffolds Novel biomaterials
