Silver nanoparticles capped with N-(4-amino-3,5-diphenyl-3H-thiazol-2-ylidine)benzamide is synthesized by simple chemical reduction method, prepared by treatment of aqueous silver ions with hot ethanolic solution of N-(4-amino-3,5-diphenyl-3H-thiazol-2-ylidine)benzamide. The size and shape of obtained silver nanoparticles are spherical and uniform with average size of 34 nm and are characterized by using UV-visible, FTIR, XRD, SEM and TEM studies. The capped silver nanoparticle showed significant inhibitory activity against various human pathogenic bacteria with different doses of 25, 50, 75 and 100 μg. The synthesized silver nanoparticle capped compound was potent inhibitory agent when compared with standard antibiotic ciprofloxacin.
采用简单的化学还原法合成了用N-(4-氨基-3,5-二苯基-3H-噻唑-2-亚基)苯甲酰胺包覆的银纳米粒子,该方法是通过将水合银离子用N-(4-氨基-3,5-二苯基-3H-噻唑-2-亚基)苯甲酰胺的热乙醇溶液处理而制备的。获得的银纳米粒子的形状为球形且均匀,平均尺寸为34 nm,并通过紫外-可见光谱、傅里叶变换红外光谱、X射线衍射、扫描电子显微镜和透射电子显微镜进行表征。这种包覆的银纳米粒子对各种人源病原菌显示出显著的抑制活性,剂量分别为25、50、75和100 μg。与标准抗生素环丙沙星相比,合成的银纳米粒子包覆化合物显示出强大的抑制剂效力。
