Preparation of gold nanoparticles by chemical reduction method.

In this paper, Gold nanoparticles were prepared by chemical reduction method using materials Gold chloride (HAuCl4/H2O) and deionized water, This method has proven its effectiveness by obtaining gold nanoparticles with sizes (9-11) nanometers. Moreover, the resultant nanoparticles have no inclination to clump together and are distributed at the nanoscale. The process's cheap cost of execution is also encouraging. The major benefit of chemical reduction is that it is characterized by great efficiency in synthesis. [ABSTRACT FROM AUTHOR]
