Discuss the physical, chromatographic and spectroscopic methods of characterization of Quercetin.
Answers
Research on biofilms has developed into interdisciplinary work, in which scientists from different fields are involved. This review summarizes the state- of-the-art including models due to different aspects of biofilms. Techniques for characterization of surfaces and interfaces, e.g. microscopic, spectroscopic and microsensoric methods will be presented. In addition, procedures that involve sampling of biofilms and subsequent separation of the components for their analysis are a part of this article. Analytical methods are summarized for the investigation of extracellular polymeric substances (EPS), mainly polysaccharides beside proteins in the microbial host. Finally, procedures for the analysis of minerals as components of biofilms are presented.
