| Abstract Scope |
Bacterial biofilms are surface-associated communities of bacterial cells embedded in an extracellular matrix (ECM). Biofilm cells can survive and thrive in various natural environments causing tenacious problems in healthcare and industry. From a materials science point of view, biofilms can be considered as soft, viscoelastic materials and exhibit remarkable mechanical resilience. In this talk, I will discuss about our recent progress in using Vibrio cholerae, the causal agent for the pandemic cholera, as a model organism to investigate biofilm mechanics in both linear and nonlinear rheological regime and the role of each constituent matrix component. I will further discuss how we develop technologies to remove biofilms from surfaces or to transfer intact biofilms. In the second part of my talk, I will show how we design new underwater glues based on the molecular principles we learned from bacterial biofilms. |
