Synthesis of Selenium Sulfide Nanoparticles in Polysaccharide Arabinogalactan and Starch Matrices

New water-soluble SeS2 containing nanocomposites are obtained via ion-exchange interaction between selenous acid and ammonium sulfide in water using natural arabinogalactan and starch polysaccharides as nanoparticle stabilizers. The transmission electron microscopy, X-ray diffraction analysis, and dynamic light scattering data show that nanocomposites are formed as spherical crystalline SeS2 nanoparticles 5–140 nm in size, dispersed in polysaccharide matrices. The type of stabilization matrix and ratio of reactants have a decisive influence on the nanomorphological properties of the materials obtained.
