| The development of ecofriendly and non-toxic process for synthesis of silver nanoparticles is a great
concern in the field of nanotechnology. In the present study, a reliable approach for the synthesis of Ag-
NPs was investigated using the aqueous extract of three marine macroalgae, Ulva flexuosa (Chlorophyta),
Colpomenia sinuosa (Phaeophyceae) and Gracilariopsis persica (Rhodophyta). The complete reduction of
silver ions was observed after 24 h of reaction at 25°C. The formation of Ag-NPs was analysized by UVVis
spectrum, Transmission Electron Microscopy (TEM), Scanning Electron Microscopy (SEM) and Xray
diffraction (XRD). Our finding demonstrated that U. flexuosa, C. sinuosa and G. persica have the
potential of silver nanoparticles production in a media containing AgNO3 at room temperature. |
