abstract
This study investigates the antibacterial efficacy of cotton fabrics coated with zinc oxide nanoparticles (ZnO NPs) using a sonochemical method, focusing on their action against Staphylococcus aureus and Escherichia coli. Zinc oxide nanoparticles were applied to the textiles through a high-frequency ultrasound process, ensuring a uniform coating. The treated fabrics exhibited significant antibacterial activity, with 84.9% reduction in E. coli colony-forming units (CFU) and 89.5% reduction in S. aureus CFU. The zone of inhibition tests further confirmed these findings, showing clear bacterial growth suppression around the textile samples. The results suggest that ZnO NP-coated cotton textiles, produced via sonochemical methods, possess strong antibacterial properties against both Gram-positive and Gram-negative bacteria, making them promising for medical and hygienic applications.
