Extracellular synthesis of silver nanoparticles by a marine alga, Sargassum wightii Grevilli and their antibacterial effects.
Extracellular synthesis of silver nanoparticles by a brown seaweed, Sargassum wightii is reported in this study. The silver nanoparticles synthesized by this method were characterized by means of UV-Vis spectroscopy, FT-IR, XRD and HR-TEM. Antibacterial studies were carried out using the bacteriae isolated from the infected silkworm. The recorded antibacterial effect of silver nanoparticles was found more potent when compared to the chemically synthesized silver nanoparticles and it is expected to be biocompatible.
