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 (312 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 the Escherichia coli.
I. INTRODUCTION
Tissue engineering has received extensive attention in
recent years as an emerging and rapidly growing field.
