Bacterial Exopolysaccharides as Reducing and/or Stabilizing Agents during Synthesis of Metal Nanoparticles with Biomedical Applications

Figure 1

Structure of some microbial exopolysaccharides. The chemical structure of diverse microbial EPSs can differ in functional groups or sugars branched in the main chain structure. (a) Hyaluronic acid, (b) curdlan, (c) xanthan, (d) dextran, and (e) gellan. The “n” indicates the polymerization degree of the polysaccharides, and it can vary significantly from bacteria strain and culture conditions.
