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.
本研究报道了用一种褐藻——半叶马尾藻进行银纳米颗粒的胞外合成。通过该方法合成的银纳米颗粒用紫外可见光谱、傅里叶变换红外光谱、X射线衍射和高分辨透射电子显微镜进行了表征。使用从受感染家蚕中分离出的细菌进行了抗菌研究。结果发现，与化学合成的银纳米颗粒相比，记录到的银纳米颗粒的抗菌效果更强，并且预计具有生物相容性。
