Synthesis of Nickel Nanoparticles Using Ionic Liquid-Based Extract from Amaranthus viridis and Their Antibacterial Activity

Abstract

The bioactive components of Amaranthus viridus were extracted in the present study using 1-ethyl-3-methyl imidazolium acetate [C3MIM] Ac and a microwave. The plant extract was used to synthesize nickel nanoparticles (Ni NPs), whose production was validated by UV/Vis spectrophotometry. The nanomaterials were characterized by X-ray diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy, and thermogravimetric analysis (TGA). The morphology was identified using Field Emission Scanning Electron Microscopy (FESEM), while the particle size and zeta potential were examined using Dynamic Light Scattering (DLS). Nickel nanoparticles were utilized for anti-bacterial activity.
