Electron paramagnetic resonance characterization of the exopolysaccharide layer produced by bacteria

In order to establish a method to characterize the structural heterogeneity of the bacterial surface, research was conducted with a combination of experiments based on electron paramagnetic resonance (EPR) concentration-imaging (CI) and the modeling of translational diffusion with local restrictions. The benefits and drawbacks of this approach are discussed for the Vibrio sp. exopolysaccharide (EPS) layer.
