Optical, Structural, and Antimicrobial Study of Gold nanoparticles Synthesized Using an Aqueous Extract of Mimusops elengi Raw Fruits

Abstract

Gold nanoparticles (AuNPs) has been synthesized via a green route using an aqueous extract of Mimusops elengi raw fruits. The phytochemicals of the fruit help in stabilizing and capping of the nanoparticles. The formation and stability of the synthesized samples has been explained based on results that we obtain from UV-Visible spectroscopy, Fourier Transform Infra-Red (FTIR) spectroscopy, Dynamic Light Scattering (DLS), X-ray diffraction (XRD), scanning electron microscopy (SEM). Further, the positive results of the antimicrobial test add one more novelty to this work. The axiom of this work is the synthesis of stable AuNPs without using any external stabilizing or reducing agents. The formation of AuNPs with the help of photochemical present in Mimusops elengi is yet another important aspect of this work, which provides an eco-friendly method for the synthesis of AuNPs, which can be used extensively because of its non-hazardous condition.
