The aim of this study is to synthesis gold nanoparticles with an ecofriendly method and to characterize it. Gold nanoparticles were prepared by the reduction of HAuCl(4) by using citrus fruits juice extract as the reducing and stabilizing agent. Citrus grapes, Citrus lemon, and Citrus Orange juice extracts were used for the synthesis. Various concentrations of fruit extracts were added with 1.0mM hydrogen tetracholoroaureate (III) hydrate (HAuCl 4 3H 2 O) by sonication method. The gold

The particles were found to be spherical in nature and it varied from 45nm to 70nm. It was found that the size varid with the concentration. UV absorption studies were done to confirm the absorbance range of the nanoparticles. Surface morphological studies were done with FESEM and AFM. This is a novel and simple method for the biological synthesis of gold nanoparticles with potent physical applications.
