Biosynthesis of silver nanoparticles using marine sponge extract Haliclona was carried out. Marine sponges' extracts are responsible for the reduction of silver nitrate solution. Silver nanoparticles synthesized using fresh and dry marine sponge. Experimental factors including, time duration, pH, temperature were optimized. Silver nanoparticles were characterized by UV-Visible spectrophotometry. The sizes of synthesis silver nanoparticles were 27-46 nm and confirmed by scanning electron microscopy (SEM). X-ray diffraction (XRD) crystallography indicated the silver nanoparticles crystalline nature. Fourier transform infrared spectroscopy (FT-IR) was revealed the functional groups of extract of Haliclona, which are capable of reduction of silver nanoparticles. This method is a cost-effective, eco-friendly and nontoxic procedure..
