By controlling the size and shape of silver nanoparticles, the properties of silver nanoparticles can be modulated, which drives the development of a novel green synthetic route. The application of silver nanoparticles including biosensors, catalysis, and antimicrobials has already been reported (Nam et al. 2003; Sondi and Salopek- Sondi 2004). Several chemical methodologies are used to synthesize silver nanoparticles in aqueous and organic solvents using reductants such as borohydride, citrate, ascorbate and elemental hydrogen, and stabilizers to prevent agglomeration of silver colloids. However, these chemical processes utilize some toxic chemicals. Therefore, eco-friendly approaches are pertinent for environmentally
