<i>Pomegranate Peel</i> Extract-Mediated Green Synthesis of ZnO-NPs: Extract Concentration-Dependent Structure, Optical, and Antibacterial Activity

<div>(a) Selected plate images of antibacterial activity tests of ZnO-NPs prepared using 20, 30, and 40 mL PPE (from the bottom to the top: Z20, Z30, and Z40) against <i>S. aureus</i> (left images) and <i>E. coli</i> (right images). Disks: (1) ZnO-NPs 50 mg/mL per disc; (2) ZnO-NPs 100 mg/mL per disc; (3) ZnO-NPs 200 mg/mL per disc; (4) Azithromycin antibiotics (positive control); (5) distilled water (negative control). (b) Histogram illustration for the corresponding zone of inhibition data; bars represent the standard error of the mean (<i>n</i> = 2).</div>
