The Effective Parameters in Silver Nanoparticles Synthesized by the Chemical Reduction Method

In recent years, silver nanoparticles have attracted the attention of many researchers due to its special physical and chemical properties. Much of these properties are due to the high surface to volume ratio of the particles. These properties make silver nanoparticles as one of the most widely used nanoparticles in industry as well as medicine. There are different methods of silver nanoparticles synthesis, among those; chemical reduction is the most common method because of its simplicity and ability to control of the shape and size of the nanoparticles. In chemical reduction method the size and morphology of the particles can be easily controlled, by changing parameters such as the concentration of silver salt, reducing agent and stabilizer, temperature, pH and reaction time. In this article it has been tried to have a short review on the parameters that affect size and morphology of the silver nanoparticles, synthesized by the reduction method.
