Abstract Size, shape and distribution-controlled silver nanoparticles (AgNps) were produced by a rapid and efficient method either in solvent or in polymer matrix by which the silver ion is reduced and a polymer matrix is simultaneously generated in the presence of various photoinitiators by the means of UV light. 2-Mercaptothioxanthone (TX-SH), Thioxanthone (TX) and TX + Thiophenol were used as photoinitiator systems for the polymerization of PEGMEA/PEGDA monomer mixture in the presence of AgNO3 salt. As a summary of results, it is important to note that the size and distribution of Nps depend on the photoreducing species. Therefore TX-SH, due to thiol functionality in its structure, helped production of he 7–40 nm size and distribution-controlled AgNps in polymer matrix. In-situ prepared AgNps/Polymer nanocoatings exhibited a reflected silver mirror view as a result of aggregation depending on the irradiation time. Antibacterial efficiency and susceptibility of AgNps containing nanocomposite films were examined for t E. coli, P. aeruginosa, S. aureus and B. cereus. Obtained antimicrobial results show that photochemically prepared nanocomposites considerably increase the antimicrobial activity on Gram negative bacteria compared to Gram positive bacteria.

通过硫醇-丙烯酸酯光聚合制备AgNp纳米复合薄膜的简便且通用的途径：抗菌活性的测定

摘要 尺寸、形状和分布控制的银纳米粒子 (AgNps) 是在溶剂或聚合物基质中通过一种快速有效的方法生产的，通过这种方法，银离子被还原，并在各种光引发剂的存在下同时生成聚合物基质。紫外线的手段。2-巯基噻吨酮 (TX-SH)、噻吨酮 (TX) 和 TX + 硫代苯酚用作光引发剂体系，用于在 AgNO3 盐存在下聚合 PEGMEA/PEGDA 单体混合物。作为结果的总结，重要的是要注意 Nps 的大小和分布取决于光还原物种。因此，由于其结构中的硫醇官能团，TX-SH 有助于在聚合物基质中产生 7-40 nm 尺寸和分布控制的 AgNps。原位制备的 AgNps/聚合物纳米涂层显示出反射的银镜面，这是根据照射时间聚集的结果。针对大肠杆菌、铜绿假单胞菌、金黄色葡萄球菌和蜡状芽孢杆菌，检测了含有纳米复合膜的 AgNps 的抗菌效率和敏感性。获得的抗菌结果表明，与革兰氏阳性菌相比，光化学制备的纳米复合材料显着提高了对革兰氏阴性菌的抗菌活性。
