摘要
Synthesis of nanomaterials by biological approach is innovative,cheaper and environmental friendly and requires less-labor.In this regard,the present study focused on the synthesis of silver nanoparticles from the extract of Sargassum tenerrimum.Synthesized silver nanoparticles were well-characterized by UV-Visible Spectroscopy(UV-Vis),Fourier-Transform Infra-red Spectroscopy(FT-IR),Transmission Electron Microscopy analysis(TEM)and Dynamic Light Scattering(DLS).It was found that spherical shaped nanoparticles of size 20 nm were found in TEM analysis and showed effective anti-bacterial activity against standard reference strains.Altogether,extracts from seaweed were screened for phytochemicals followed by FT-IR prediction to reveal chemical functional groups present.The results showed that the anti-bacterial activity of silver nanoparticles was comparably higher than the phytochemicals present.Therefore,the present study elucidates silver nanoparticles can play a vital role in nano-based therapy in future.
