In the present work, we report the antibacterial activity of silver nanoparticles (AgNP) coated with the surfactants para-amino-N-((1-decylpyridin-1-ium bromide)-4-yl) benzamide and para-amino-N-((1-dodecylpyridin-1-ium bromide)-4-yl) benzamide (P10 and P12, respectively). P10 and P12-coated AgNP were stable, as confirmed by ultraviolet–visible spectrophotometry, transmission electron microscopy, and other surface activity parameters. Both P10 and P12 and the coated AgNP formulations were investigated for their activity against sulfate reducing bacteria (SRB). Overall, our results showed the importance of coating AgNP with surfactants (P10 and P12) in the design and development of new biocides against SRB.

对氨基-N-((1-烷基吡啶-1-溴化铵)-4-Yl)苯甲酰胺表面活性剂和表面活性剂包覆的银纳米粒子对硫酸盐还原菌的抑制作用

在目前的工作中，我们报告了涂有表面活性剂对氨基-N-((1-decylpyridin-1-ium bromide)-4-yl) 苯甲酰胺和对氨基-N-表面活性剂的银纳米粒子 (AgNP) 的抗菌活性。 ((1-dodecylpyridin-1-ium bromide)-4-yl) 苯甲酰胺（分别为 P10 和 P12）。紫外-可见分光光度法、透射电子显微镜和其他表面活性参数证实，P10 和 P12 包覆的 AgNP 是稳定的。研究了 P10 和 P12 以及涂覆的 AgNP 制剂对硫酸盐还原菌 (SRB) 的活性。总体而言，我们的结果表明，在设计和开发针对 SRB 的新型杀菌剂时，用表面活性剂（P10 和 P12）包覆 AgNP 的重要性。
