Abstract	Currently, the mechanism of biological nanoparticles synthesis is not fully understood. We proposed an ecofriendly method for gold nanoparticles (AuNPs) synthesis using plant extractsand electrochemical characterization. The reduction of the metal ions through leaf extract leading to the formation of AuNPs of fairly well-defined dimensions. This green chemistry approach toward the synthesis of AuNPs has many advantages such as, ease with which the process can be scaled up, economic viability, etc. Leaves extract is found suitable for the green synthesis AuNPs. Average crystal size calculated from SEM, respectively. The particle size ranging from 100 to 300 nm and the shape of the plate and spherical structures could be controlled by changing the reaction temperature and leaf broth concentration. The concentrations of leaves extract and metal ion are playing an important role in the green synthesis of AuNPs. The spectroscopic characterizations from Cyclic voltammetry (CVs), Electrochemical impedance spectroscopy (EIS) and UV-visible absorption spectra support the formation and stability of the biosynthesized AuNPs. This simple, efficient and rapid green synthesis of AuNPs can be used in various biomedical and biotechnological applications. This environmentally friendly method of biological AuNPs synthesis can potentially be applied in various products that directly come in contact with the human body, such as cosmetics, foods, and consumer
