Biofilm engineering is a research area that focuses on the manipulation and control of biofilms, which are communities of microorganisms that adhere to surfaces and create a protective layer of extracellular polymeric substances. Biofilms play a significant role in various industries such as water treatment, food processing, and medical fields. Researchers in this area aim to understand the formation, structure, and function of biofilms in order to develop strategies to control and manipulate their behavior. This may involve developing novel materials, antimicrobial agents, or techniques to prevent biofilm formation or disrupt existing biofilms. Ultimately, biofilm engineering aims to improve the efficiency and safety of industrial processes, medical devices, and environmental systems.
