Evaluation of the antibacterial activities of face masks coated with titanium dioxide nanoparticles.

ABSTRACT: To control infectious diseases, various applications of nanotechnology have been used to enhance the self-cleaning and antibacterial properties of materials. This study aimed to evaluate the antibacterial properties of face masks coated with TiO2 nanoparticles. The antibacterial efficacies of cloth face masks coated with TiO2 were measured by inoculating them in bacterial suspensions (10⁵ CFUs from both E. coli and S. aureus). The results showed that TiO2 nanoparticle solutions (at 2%) reduced the starting inoculum of 10⁵ CFUs (5 log cfu/cm²) of E. coli and S. aureus to 1.3 and 1.68 log, respectively, with antibacterial activities of 3.7 and 3.34 log, respectively. Furthermore, at a 1% concentration, the antibacterial activities against E. coli and S. aureu
