three model microbes, Gram-positive bacteria Staphylococcus aureus, Gram-negative bacteria Escherichiacoli and common airborne fungus Aspergillus niger. No viable bacterial colonies or fungal spores could be detected in the areas surrounding test samples of the antimicrobial paper. Gram-negative
bacteria Escherichiacoli were found to be inhibited in an area that is 239% and 163% the area of the paper sample under different room lighting conditions, i.e., halogen and fluorescent lamp illumination, respectively. For Gram-positive bacteria Staphylococcus aureus the zones of inhibition surrounding
) 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 Escherichiacoli (E. coli) [5]. An increase

due to enterohaemorrhagic E. coli (Escherichiacoli) have a low incidence but can have severe and sometimes fatal health consequences, and thus represent some of the most serious diseases due to the contamination of water and food. New, fast and simple devices that monitor these pathogens are
Foodborne illness is primarily caused by pathogenic microorganisms among which Campylobacter, Salmonella, Listeria monocytogenes, and Escherichiacoli O157: H7 are responsible for the majority of foodborne outbreaks [1][2], and most of the recalls of food products have implicated these pathogens [3].
