Green Synthesis and Characterization of Urtica dioica Mediated Silver Nanoparticles for Antibacterial Application

Al-Shehri HS

Green synthesis of Ag-NPs (silver nanoparticles) has revolutionized the area of nanotechnology consistently and bio-based silver nanoparticles have emerged as efficient therapeutic tool in the field of biomedical science. The nanoparticles were synthesized via green route approach by Urtica dioica leaf extract. The biosynthesized Ag Nanoparticles (NPs) were analyzed by Powder XRD, FTIR, SEM with EDX, UV-vis and HRTEM analysis. The antimicrobial studies of the synthesized Ag-NPs were tested against Bacillus subtilis, and Staphylococcus aureus (gram-positive) and Psuedomonas aeruginosa, and Shigella dysenteriae (gramnegative) bacterial pathogens using the disc diffusion method. The prepared nanoparticles demonstrated strong antimicrobial activity against all microbial strains examined with varying concentrations.
