In view of their wide applicability in electronics, catalysis, chemistry, energy, and medicine, there is an increased commercial demand for nanoparticles (NPs) in biotechnology. Metallic NPs are traditionally synthesized by wet chemical techniques that reportedly use toxic and inflammable agents. Herein, we describe an eco-friendly technique for green synthesis of silver (Ag) NPs from silver nitrate (AgNO3) solution using leafy extracts of Mimusops elengi (M. elengi) as reducing as well as capping agent. The NP preparations were characterized using UV–VIS absorption spectroscopy, X-ray diffraction (XRD), Fourier Transform infrared spectroscopy (FTIR) and scanning electron microscopy (SEM) analyses. XRD and SEM investigations showed a 50nm average particle size as well as structural configurations. The synthesized NPs also exhibited antibacterial potentials against ATCC strains of Staphylococcus aureus and Escherichia coli. Our study highlights the importance of the development of valueadded products from M. elengi for potential applications in biomedicine and nanotechnology-based industries.
