AB  - Design and synthesis of bactericidal and fungicidal agents is very important to 
      protect human beings from different diseases. Silver nanoparticles (AgNPs) 
      possess good bactericidal properties. Synthesis of these nanoparticles (NPs) via 
      green route is cost-effective and environmentally harmonious as compared to the 
      chemical and physical approaches. In this work, AgNPs were synthesized through 
      green synthesis method using Populus ciliata leaf extract. The synthesized AgNPs 
      were characterized by x-ray diffraction (XRD), ultraviolet-visible (UV-Vis) 
      spectroscopy, Fourier-transform infrared (FT-IR) spectroscopy, scanning electron 
      microscopy (SEM), transmission electron microscopy (TEM), and energy dispersive 
      x-ray (EDX) techniques. The XRD pattern depicted the characteristic Bragg's peaks 
      of (111), (200), (220), and (311) planes which are the features of face centered 
      cubic (FCC) geometry of the synthesized AgNPs. TEM micrographs revealed the 
      spherical shaped particles having average size of 4 nm. The AgNPs showed 
      inhibitory effects against selected gram positive (Staphylococcus epidermidis and 
      Streptococcus pyogenes) and gram negative bacteria (Klebsiella pneumoniae, 
      Serratia marcescens, and Pseudomonas pseudoalcaligenes). The maximum zone of 
      inhibition (26 mm) was observed for gram negative bacterium (Serratia marcescens) 
      when 25 mg/ml solution of AgNPs was used and for similar concentration of these 
      NPs, the maximum zone of inhibition (25 mm) was observed against gram positive 
      bacteria (S. pyogenes). The results indicated good bactericidal potential of the 
      synthesized AgNPs. RESEARCH HIGHLIGHTS: Populus ciliata leaf extract mediated 
      synthesis of AgNPs. Transmission electron microscopy analysis revealed very small 
      size of the synthesized AgNPs (4 nm). The synthesized AgNPs were found very 
      effective against various bacterial pathogens.
