Abstract: Green synthesis of noble metal nanoparticles is a developing area of current nanotechnology research. In this paper we report the eco-friendly biosynthesis of Silver nanoparticles (AgNPs) using the aqueous extract of brown seaweed Padina Tetrastromatica as reducing agent and stabilising agent. . The reduction of silver ions occurred when silver nitrate solution was treated with aqueous extract of seaweed at 60 -C. The AgNPs obtained were characterized by UV-Visible Spectroscopy, HR-TEM, SAED, EDAX, XRD and FTIR techniques. The formation of silver nanoparticles is confirmed by the appearance of signatory brown colour of the solution and a characteristic peak at 424 nm in the UV-Vis spectra. The high crystallinity of nanoparticles is evident from bright circular spots in the SAED pattern and peaks in the XRD pattern. TEM images revealed that the synthesised nanoparticles are spherical with size in the range 5-35 nm. FTIR spectrum indicates the presence of different functional groups in capping the nanoparticles.
