• model organisms. The nanofibers fabricated by this method showed obvious antibacterial activity. Electrochemical properties were characterized based on cyclic voltammetry measurements. The CV results showed redox peaks corresponding to the Fc+/Fc couple, which suggested that Fc molecules encapsulated

• a polymer provides different properties compared with applying Fc alone. The incorporation of Fc in a polymeric matrix can improve the dispersion of Fc, increasing the catalyst effect and antibacterial activity of hybrid nanofibers. However, the current reports mainly focus on the preparation and

• ) nanoparticles embedded into a paper matrix have been reported as exhibiting antibacterial properties [4]. Wallpaper prepared by using zinc oxide nanoparticle (~20 nm) coatings has been reported to render antibacterial surfaces that inhibit growth of bacteria such as Escherichia coli (E. coli) [5]. An increase
