Green Synthesis and Characterization of Silver Nanoparticles from Ficus palmata Forssk. and Evaluation of their Antibacterial Activity Against Resistant Bacteria

Tayyab Rehman, Hoor Shumail, Shah Khalid, Syed Inzimam Ul Haq


In the present study, the synthesis and characterization of silver nanoparticles were carried out through a green chemistry approach. The purpose was to determine the antibacterial potential of environmentally safe nanoparticles against commonly reported resistant bacteria. The nanoparticles were synthesized using the aqueous extract of Ficus palmata Forssk. leaves. The active components present in the leaf extract acted as reducing and capping agents. The method used was easy, cost-effective, eco-friendly, and less time-consuming. To determine the shape, size, and crystalline nature, the nanoparticles underwent X-ray diffraction, and scanning electron microscopy. The synthesized nanoparticles were found to be crystalline in nature and spherical in shape, with an average diameter of about 30 nm. The antibacterial activity of the silver nanoparticles (20 µl) was evaluated against a range of antibiotic-resistant bacteria using standard microbiological procedures. They were found to be effective against MRSA, Bacillus subtilis, Staphylococcus aureus, and Klebsiella pneumonia.
