Biogenic Fabrication of Iron and Zinc using Carob Seed Extract and their Antibacterial Activity

Abstract

Biogenic synthesis of iron and zinc nanoparticles from carob seed extract (C. siliqua L.) and their antibacterial activity were studied. The characteristics of the prepared nanoparticles were evaluated shapes and sizes by Field Emission Scanning Electron Microscopy (FESEM) analysis with mapping technique and energy dispersive X-ray analysis (EDX), and Fourier-transform infrared spectroscopy (FTIR) confirmed the functional group that contributes to the biogenic and antibacterial activity. The appearance of metal-oxygen bonds for both ZnO NPs and Fe2O3 NPs in spectra and the presence of zinc, iron, and oxygen in varying proportions confirm the success of the biosynthesis of the nanoparticles. Ceratonia siliqua L. extract, iron, and zinc showed high effectiveness in removing bacteria from polluted water.
