报告摘要：

Biofilms are probably the oldest and surely the most successful form of life. They exist virtually everywhere on Earth. They have a huge impact on human health, the environment, energy, agriculture, and the economics. Biofilms are composed of aggregates of microbes embedded in the matrix consisting of extracellular polymeric substances (EPS). EPS are the biomaterials produced by the bacteria, consisting of polysaccharides, proteins, and DNA. It is the major component of biofilms. It has been increasingly recognized that EPS play a fundamental role in defining the biofilm properties, many of which awaited to be discovered. So EPS are perhaps the most successful biomaterials made by Nature. Nevertheless, little is known about it. In this lecture, Prof. Cai will talk about our research related to biofilms and EPS, involving surface chemistry, a bit synthesis, characterization using mass spectrometry, and potential medical application of biofilms against biofilms.
