Biophysics of Collective Behaviour
What can we learn about collective bacterial behaviors from physics? Many aspects of bacterial interactions are inherently physical. Some examples: During biofilm growth, cells push and pull on each other, while being embedded in an elastic matrix. Understanding the molecular transport of nutrients and metabolites through the biofilm also relies on physics. Before bacteria form biofilms, their swimming motility creates fluid flows that lead to physical interactions with surfaces and other bacteria.
