Abstract—The antibacterial nanocomposites creation is a current trend against microbial contamination and microorganism’s biofilm formation. Existing methods for producing nanocomposites based on silver nanoparticles are difficult, expensive, and not environment friendly; therefore it has become necessary to develop a new method for their synthesis that didn’t have these minus. The paper discusses the possibility of silver nanoparticles synthesizing and obtains a new nanocomposite using halloysite nanotubes and ultrasound. Transmission electron microscopy revealed the silver nanoparticles presence on the inner and outer surface of halloysite nanotubes, and sample mapping showed a uniform distribution of silver nanoparticles in the nanocomposite. The antibacterial activity of the obtained nanocomposite against the strain Serratia marcescens (S. marcescens) was more than twice higher than that of the control. The swarming motility method showed that the diameter of migration of S. marcescens was 2.05 ± 0.05 cm, and in the presence of the nanocomposite, it was 1.63 ± 0.04 cm, indicating the ability of the nanocomposite to inhibit biofilm formation in these bacteria. In the future, the obtained nanocomposite can be used as an additive to various materials or as a coating protecting against bacterial contamination of various surfaces and materials.

利用超声和碱土矿合成具有抗菌性能的纳米复合材料，合成银纳米颗粒

摘要—抗菌纳米复合材料的产生是当前对抗微生物污染和微生物生物膜形成的趋势。用于生产基于银纳米颗粒的纳米复合材料的现有方法困难，昂贵且不环保。因此，有必要开发一种没有这些缺点的新方法来合成它们。本文讨论了银纳米粒子合成的可能性，并使用埃洛石纳米管和超声波获得了一种新的纳米复合材料。透射电子显微镜显示在埃洛石纳米管的内表面和外表面上存在银纳米颗粒，并且样品作图显示了纳米复合物中银纳米颗粒的均匀分布。所得纳米复合材料对菌株的抗菌活性粘质沙雷氏菌（S. marcescens）比对照高两倍以上。蜂拥蠕动方法表明，迁移的直径粘质沙雷氏菌为2.05±0.05厘米，并在纳米复合材料的存在，它是1.63±0.04厘米，表明该纳米复合材料的，以这些细菌抑制生物膜形成的能力。将来，所获得的纳米复合材料可以用作各种材料的添加剂或用作防止各种表面和材料受到细菌污染的涂层。
