Abstract: The present study is aimed to investigate the ability of Kappaphycus alverazii to reduce silver nitrate into silver nanoparticles. The sea weed, Kappaphycus alverazii was collected from the coasts of Rameswaram, Ramanathapuram district of Tamil Nadu, India. The sea weed broth was prepared and resuspended in an aqueous solution of 1mM silver nitrate in 250ml Erlenmeyer flask. This mixture is known as reaction medium. The reduction of silver nitrate into silver nanoparticles in the reaction medium was monitored by keeping it in an incubator cum shaker with 250 rpm at 27°C for 96hours. From this reaction medium, a small aliquot of the sample was used for the characterization of silver nanoparticles through UV-Visible spectroscopic analysis, Fourier Transform Infrared (FTIR) spectral analysis, X-Ray diffraction (XRD) analysis, Scanning Electron Microscopic (SEM) and Energy Dispersive X-ray (EDX) analyses. The time dependant spectral analysis provides the evidence of synthesis of nanoparticles. The FTIR analysis explains the stability of silver nanoparticles that are synthesized by the sea weed. The XRD analysis gives the structural information of nanoparticles. The SEM and EDX analyses confirmed the synthesis of nanoparticles. Thus eco-friendly synthesis of silver nanoparticles is achieved using the sea weed, Kappaphycus alverazii, as there is no involvement of toxic chemicals as reducing agents in this biological synthesis.
