An exploratory and promising research project based on a recent discovery — that polymers can regulate the structure and function of biological systems — is generating a new field of “living” soft matter. The researchers discovered that polymers can regulate the structure and function of biological materials, ranging from sub-cellular proteins to extracellular hydrogels to populations of cells, through entropic interactions. These results have generated a new field at the interface of biology, physics, and chemistry whose findings will enable the control and design of novel materials. The project goals are to define the principles underlying structural transition in intra-, extra-, and multi-cellular systems and to use this knowledge to control and design novel bio-inspired soft materials.
The research team is composed of Clifford Brangwynne (CBE), Howard Stone (MAE) and Andrej Košmrlj (MAE) who will focus on confined polymer dynamics and phase transitions. Other team members include Bonnie Bassler, (MolBio) and Sujit Datta (CBE) who will investigate structural transitions in biological and bio-inspired polymer liquids and polymer networks using experiments, theory, and simulations.
