    Biosynthesis of Silver Nanoparticle by Amphiroa anceps (Lamarck) Decaisne and Its Biomedical and Ecological Implications
    Author(s): Suparna Roy and Anantharaman PSuparna Roy and Anantharaman P

    The present study synthesized silver nanoparticles by using seaweed extract and tested it against clinical bacterial pathogens and also with seeds to assess its friendly potential to germination. The biosynthesized Silver Nanoparticles was characterized with UV-Visible Spectrophotometer, Fourier-Transform Infrared Spectroscopy (FT-IR), Scanning Electron Microscopy (SEM), Dynamic Light Scattering (DLS) and X-ray Diffraction study. Antibacterial activity was evaluated using agar disc diffusion and the seed germination test was done with standard protocol. The nanoparticles exhibited highest antibacterial activity against Escherichia coli (0.95 ± 0.057 cm), followed by Klebsiella pneumoniae (0.63 ± 0.05 cm), as compared to antibiotic Chloramphenicol (5 mg/ml). The per cent seed germination was 75% and 80% respectively in Abelmoschus esculentus and .. View More»
