Abstract
Molar mass parameters of galactose-containing polysaccharides constituting composites with noble metal nanoparticles have been determined by means of Size-exclusion chromatography (SEC). The composites are self-assembled via specific interaction of the biopolymers with the surface of the metal nanoparticles. The metal content significantly influences the molar mass parameters of the stabilizing polysaccharides. The change of the polymer of polydispersity is due to their redox interaction with the metal ions as well as due to the alkaline-induced degradation. Increasing the nanoparticles number results in the enhanced macromolecules aggregation.
