This research involved the synthesis of ZnO:Al nanoparticles with varying doping levels (0%, 4%, 6%, and 8%). Subsequently, a comprehensive analysis was conducted on the samples to evaluate their antibacterial, structural, morphological, and optical characteristics. XRD analysis confirmed a hexagonal Wurtzite structure in all samples, with peak shifts toward higher angles as aluminum doping increased, indicating a reduction in crystallite size. SEM images showed an increase in particle size and improved homogeneity. UV-Vis analysis showed that an increase in aluminum doping led to a rise in the optical band gap from 3.62 eV in pure ZnO to 3.90 eV, suggesting alterations in the material’s electronic structure. The antibacterial efficacy of the 8% ZnO:Al nanoparticles was assessed against Staphylococcus aureus and Escherichia coli, revealing that the 8% sample demonstrated the strongest antibacterial properties, with more significant inhibition zones observed for S. aureus.
