Bactericidal efficacy of electrospun pure and Fe-doped titania nanofibers

This paper reports the development of nonwoven nanofibers of pure and iron-doped titanium dioxide (TiO₂) and evaluation of their antimicrobial attributes for using them as disinfectant gauze for wound healing upon brief activation by ultraviolet/infrared (UV/IR) illumination. It was found that the fibers exhibited superior bactericidal affinity when exposed briefly (3–12 s) to either multiphoton laser or infrared radiations. On the other hand, exposure to a UV beam for up to 20 min was not effective in mitigating the bacterial colonization of theEscherichia coli.
