Abstract

Titanium oxide (TiO 2) nanoparticles (NPs) in their two forms, anatase and rutile, were synthesized and deposited onto the surface of cotton fabrics by using ultrasonic irradiation. The structure and morphology of the nanoparticles were analyzed by using characterization methods such as XRD, TEM, STEM, and EDS. The antimicrobial activities of the TiO 2-cotton composites were tested against Escherichia coli (Gram-negative) and Staphylococcus aureus (Gram-positive) strains, as well as against Candida albicans. Significant antimicrobial effect was observed, mainly against Staphylococcus aureus. In addition, the combination of visible light and TiO 2 NPs showed enhanced antimicrobial activity.
