Green Synthesis of Silver Nanoparticles by Sinorhizobial Octasaccharide Isolated from Sinorhizobium meliloti

摘要

In recent years, noble metal nanocrystals have been the subject of intense research in chemistry and physics due to their nano-size dimensions. Due to their quantum size effects and surface effects, nanocrystals can exhibit novel electronic, magnetic, chemical and structural properties and have the potential for a wide array of significant applications. However, development of straightforward and versatile methods for the preparation of mono-dispersed silver nanocrystals using cheap and nontoxic chemicals, environmentally benign solvents, and renewable materials remains a chellenge.
