Green synthesis and characterization of silver nanoparticles using red apple (malus domestica) fruit extract at room temperature

The present work reports on simple and effective ecofriendly approach for the synthesis of silver nanoparticles (AgNPs) from silver nitrate using Malus domestica (red apple) fruit. The fruit extract act as both reducing and capping agents. The synthesized AgNPs were characterized using various instrumental techniques including ultraviolet-visible spectroscopy (UV-Vis), Fourier transformed infrared spectroscopy (FTIR), x-ray diffraction (XRD), scanning electron microscope (SEM), energy dispersive spectroscopy (EDS) and dynamic light scattering (DLS). Surface Plasmon Resonance (SPR) for AgNPs was observed at 422 nm. The synthesized AgNPs were found to be flower-like in shape with average diameter of 145 nm. The zeta potential of AgNPs was found to be -65.0 mV. This large negative zeta potential value indicates repulsion among AgNPs and their dispersion stability.
