Synthesis of gold nanoparticles using fruit waste

In the present work we have utilized fruit extracts (pomegranate, jack fruit) as an alternative, effectual, low-cost and environment friendly green synthesis method to produce well-defined geometries of gold nanoparticles at room temperature (30 °C) having unique structural corelated optical property. The phytochemicals present in the aqueous leaf or fruit extract acted as a reducing agent and stabilization is also achieved with other organic molecules. The generated AuNPs and were characterized by Transmission electron microscopy (TEM), UV-Visible spectroscopy, dynamic light scattering (DLS) and Zeta potential. Selected electron area diffraction (SEAD) pattern showed the particles to be crystalline in nature, with a face-centered cubic (fcc) structure. The morphology and average size of particles were analyzed by TEM measurements and DLS.
