Synthesis of Silver Nanowires by 5-Hydroxy-Tryptophan

Silver nanowires in large quantities can be obtained by 5-hydroxy-L-tryptophan through a simple method in the absence of a surfactant and seed. The influences of different experimental parameters on the morphologies of silver nanoproducts in such an environmentally friendly synthesis were investigated. Different molar ratio of reactants which can results different size and shape of silver nanoparticles. The high temperature, the acid or alkaline condition is not to facilitate formation of the nanowires. This simple and eco-friendly preparation method of silver nanowires can decrease the synthetic cost and broaden the research and application areas of silver nanowires.
