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.

双（2-苯乙基）二硒代次膦酸钠合成阿拉伯半乳聚糖稳定的硒纳米颗粒及其抗菌活性

在天然多糖阿拉伯半乳聚糖作为纳米颗粒的稳定剂存在下，通过在水性介质中氧化双（2-苯乙基）二硒代次膦酸钠，合成了含有 0.8-3.9% Se 的水溶性元素硒纳米复合材料。使用一系列物理化学研究方法（TEM、XRD、IR 光谱），发现纳米复合材料形成为大小为 31-78 nm 的无定形硒球形颗粒，分散在多糖基质中。对于含有 3.9% Se 的纳米复合材料，对细菌植物病原体 Clavibacter michiganensis subsp. 具有显着的抗菌活性。sepedonicus 被证明。
