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.
