摘要
Though there are a numerous methods for chemical synthesis, biogenic synthesis of nanoparticles offers an attractive alternative to chemical synthesis methods. Therefore scientists are continuously engaged in searching hazard free, environment friendly methods of synthesis of nanoparticles with tailor-made structural properties using benign starting materials. Recently several groups have achieved success in the synthesis of Ag, Au, Pd nanoparticles with specific shape and size using extracts obtained from micro-organisms as well as various plant extracts. It will be a highly interesting problem to modify the procedure to develop green-chemical means of synthesizing %26quot;tailor-made%26quot; monodisperse nanoparticles of single polygonal particle morphology, exclusively. The main objective of this brief article is to give an idea about the most reliable, cost-effective and environment friendly synthetic protocols for metal nanoparticles of different size, shape, composition, and with a high degree of monodispersity.
