摘要
Water-soluble elemental selenium nanocomposites containing 0.8-3.9% Se were synthesized by oxidation of sodium bis(2-phenylethyl)diselenophosphinate in aqueous medium in the presence of the natural polysaccharide arabinogalactan as a stabilizer for nanoparticles. Using a complex of physicochemical research methods (TEM, XRD, IR spectroscopy), it was found that the nanocomposites were formed as spherical particles of amorphous selenium of 31-78 nm in size, which are dispersed in the polysaccharide matrix. For the nanocomposite containing 3.9% Se, a pronounced antimicrobial activity against the bacterial phytopathogen Clavibacter michiganensis subsp. sepedonicus was demonstrated.
