Bactericidal efficacy of electrospun pure and Fe-doped titania nanofibers

Abstract

This paper reports the development of nonwoven nanofibers of pure and iron-doped titanium dioxide (Ti()2) 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 U V beam for up to 20 min was not effective in mitigating the bacterial colonization of the Escherichia coil. © 2010 Materials Research Society.
