Facile and Cost-Effective Ag Nanoparticles Fabricated by Lilium lancifolium Leaf Extract: Antibacterial and Antibiofilm Potential

In the present study one-pot green fabrication of silver nanoparticles (Ag NPs) with aqueous leaf extract of Lilium lancifolium. Synthesized Ag NPs were illustrated by UV–Vis, FT-IR, XRD, AFM and TEM analysis. A surface plasmon resonance peak was noticed at 411 nm in UV–Vis analysis. XRD patterns of Ag NPs showed high crystalline nature with face centered cubic structure. AFM and TEM analysis of Ag NPs exhibit special and anisotropic morphology with accurate particle size about 10–70 nm and average mean value of 45 nm. Ag NPs were tested for antibacterial and anti-biofilm activity against Gram positive and Gram-negative bacterial strains. The exposure to 25 µL exhibited better antibacterial activity and 50 µL significantly control the bacterial biofilm growth. Overall, the proposed green synthesis method of Ag NPs is facile, convenient, less time consuming and environmentally safe.
