Synthesis of gold nanoparticles using Coffea Arabica fruit extract

We report a simple eco-friendly process for the synthesis of gold nanoparticles (AuNPs) using aqueous extract from <i>Coffea Arabica</i> fruit. The formation of AuNPs was confirmed using absorption spectroscopy and scanning electron microscopy images. FT-IR analysis demonstrates the major functional groups present in <i>Coffee Arabica</i> fruit extract before and after synthesizing AuNPs. The Face Center Cubic (FCC) polycrystalline nature of these particles was identified by X-Ray diffraction (XRD) analysis. Taking into account the contribution of the biomass surrounding the AuNPs, dynamic light scattering (DLS) results revealed an average particle size of ~59 nm.
