Abstract
In the present study, ZnO nanoparticles (NPs) as antibacterial agents were synthesized from two different precursors in the presence and absence of ultrasound. The effect of starting materials and the method of synthesis were investigated on the properties of the ZnO NPs. The crystallographic structures of all samples were characterized by X-ray diffraction (XRD) and the strength of Zn-O bond for all the samples were determined and compared by mid-infrared (mid-IR) and far-infrared (far-IR) spectroscopy techniques. The morphology of the products was studied by transmission electron microscopy (TEM). Based on the results, the mechanisms for the growth of ZnO NPs were proposed for the samples prepared under different conditions. The antimicrobial activity of the resultant powders toward Escherichia coli as a model of microbe were evaluated by absorption and colony count methods in the form of nanofluid.
