Green synthesis of nanoparticle prevents the atmosphere from pollution and its application in various fields has become the favourite pursuit of all researchers. Recent studies have shown that several marine plants have the ability to perform as bio-factories for the production of nanoparticles. Green synthesis of (AgNPs) was achieved by using the aqueous extract of Sargassam tenerrimum and AgNO3. Reduction of silver ions into silver nanoparticles was observed as a result of the colour change from pale brown to dark brown. The synthesized nanoparticles have been characterized by UV-Vis spectroscopy, FTIR and AFM techniques. UV-Visible spectrophotometer showed absorbance peak in range of 406 nm. Infrared spectrometer (FTIR) analysis was carried out to determine the nature of the capping agents in leaf extracts. The synthesized silver nanoparticles of aqueous extract of Sargassam tenerrimum have shown good potential source of antioxidant.
