ABSTRACT
The aim of this work was to synthesis of silver nanoparticles
(AgNPs) using water soluble Polysaccharide extracted from marine algae
(L. obtusa) as reducing agents for silver ions as well as stabilizing agents
for the synthesized AgNPs. The formation of silver nanoparticles was
confirmed by Surface Plasmon Resonance (SPR) at 350 to 550 mm, by
using fourier transform infrared spectroscopy (FT-IR), X-ray diffraction
(XRD) and transmission electron microscopy (TEM). The maximum
absorption peaks are in the range of 400-420 nm. The particles were
spherical in shape in the range of 4-10 nm.
