The synthesis and characterization of ZnO NPs produced with gum Arabic and curcumin extracts are the main topics of this work. Plants and zinc nitrate are the precursors. ZnO has been described using UV, FTIR, SEM, and XRD. According to the XRD data, ZnO by Curcumin had a crystalline size of 38.92 when estimated using the Scherer equation; ZnO by Gum Arabic, on the other hand, was amorphous. According to SEM, the ZnO NP sample made with curcumin showed heterogeneity in size and shape, whereas the ZnO sample made with gum Arabic showed clumped particles that were entirely covered in proteins and some that appeared as bright protrusions. The absorption peak at 578 and 574 for ZnO using Curcumin and Gum Arabic respectively corresponds to metal-oxygen (ZnO stretching vibrations) vibration mode, which authenticated the presence of ZnO. UV absorption spectrum of ZnO nanoparticles show absorbance edge near 266 and 355 nm for ZnO by Curcumin extract and ZnO by gum Arabic extract, where the energy gap was 4.6 eV and 3.5 eV respectively. The antibacterial activity of ZnO nanoparticles was evaluated at different concentration (25,50 and75%).
