The photocatalytic analysis revealed that the synthesized ZnO NPs exhibited substantial activity under visible light, effectively degrading 90.6% of CV in an aqueous solution. The antibacterial activity of synthesized ZnO NPs was evaluated against clinically relevant bacterial strains such as Pseudomonas aeruginosa and Bacillus subtilis, revealing notable zones of inhibition. Moreover, the ZnO NPs exhibited antibiofilm activity of 96.8 ± 0.5% and 98.3 ± 0.3% against P. aeruginosa and Staphylococcus aureus, respectively.
