    A possibility of mechanochemical preparation of water-soluble nanocomposites of a plant polysaccharide arabinogalactan (AG) and element iodine has been investigated. The physical-chemical properties of iodine-containing AG nanocomposites were studied by transmission electron microscopy, elemental analysis and X-ray diffraction (XRD) analysis. Aqueous solutions of these nanocomposites were examined using optical spectroscopy and dynamic light scattering (DLS). The ζ-potential values were determined. The antimicrobial action of iodine-containing nanocomposite (13.97 % I) was investigated in relation to Escherichia coli (ATCC 25922), Pseudomonas aeruginosa (ATCC 27853), Klebsiella pneumoniae (ATCC 700603) (extended-spectrum β-lactamase), Staphylococcus aureus (ATCC 25923), Enterococcus faecalis (ATCC 29212) and Candida albicans (ATCC 90028). Its values of minimum inhibitory concentration and minimum bactericidal concentration varied from 0.5 to 5 mg/ml depending on the microorganism species. The nanocomposite based on AG and iodine was found to exhibit a pronounced antimicrobial effect. The results of the research can be considered as promising for the creation of innovative materials with antibacterial and fungicidal properties for medical and other purposes.

    研究了植物多糖阿拉伯半乳聚糖（AG）和元素碘水溶性纳米复合材料的机械化学制备的可能性。通过透射电子显微镜、元素分析和X射线衍射（XRD）分析研究了含碘AG纳米复合材料的物理化学性质。使用光学光谱学和动态光散射（DLS）检测这些纳米复合材料的水溶液，并确定ζ电位值。研究了含碘纳米复合材料（13.97% I）对大肠杆菌（ATCC 25922）、铜绿假单胞菌（ATCC 27853）、肺炎克雷伯氏菌（ATCC 700603，扩展谱β-内酰胺酶）、金黄色葡萄球菌（ATCC 25923）、粪肠球菌（ATCC 29212）和白色念珠菌（ATCC 90028）的抗菌作用。其最小抑菌浓度和最小杀菌浓度根据微生物种类的不同在0.5到5 mg/ml之间变化。基于AG和碘素的纳米复合材料表现出显著的抗菌效果。研究结果可以被认为是用于开发具有抗菌和抗真菌性能的创新材料（医疗和其他用途）的有希望的方法。
