Green Synthesized Transition Metals Nanoparticles Using Murraya koenigii Root Extract and their Comparative Study of Characterization

Plant root-mediated green synthesis of nanomaterials has been increasingly gaining popularity due to its eco-friendly nature and cost-effectiveness. Current work describes the green synthesis of silver and copper nanoparticles using Murraya koenigii roots extract as a capping agent. This study was conducted for the synthesis of nanoparticles using two exclusive salts (silver nitrate and copper sulfate) with the aid of Murraya koenigii root extract. We did comparative study of synthesized silver and copper nanoparticles using about 10 g of Murraya koenigii root. Roots were weighed separately and transferred into 250 ml beakers containing 100 ml distilled water and boiled for about 25 minutes. Solutions were then filtered to get clear extracts. The extract was taken for the reduction of Ag+ and Cu2+ ions, 10 ml of Murraya koenigii root extract was added drop wise to 10 ml of silver nitrate and copper sulphate solution (1:1ratio). The reduction reaction was studied by observing the colour change. Confirmation of silver and copper nanoparticles formation and plasmonic resonance can be found by analyzing the absorbance data of UV-VIS spectroscopy, Fourier Transform Infrared (FTIR), which were used to determine the functional groups on the cell surface that may be involved in the nanoparticle synthesis. Morphology and size of silver and copper nanoparticles were investigated using Scanning Electron Microscopy (SEM) and Transmission Electron Microscopy (TEM) experiments
