“…The antibacterial properties of ZnO in powder or nanoparticle forms have also been studied [18][19][20][21][22] and can be further enhanced by ultraviolet light activation [23]. Nanostructured ZnO has interesting properties towards the photocatalytic decomposition of organic pollutants [24] and dyes [25], while La-doped and silane-coated ZnO nanoparticles have recently shown remarkable photocatalytic action against monocrotophos [26] and tetrachloroethylene [27], respectively.…”

We found that a ZnO film of 2 µm thickness which was laser-deposited at room temperature onto a plain soda lime glass substrate, exhibits notable antibacterial activity against a biofilm of Staphylococcus epidermidis when back-illuminated by a UVA light source with a peak emission wavelength of about 365 nm. X-ray diffraction (XRD), scanning electron microscopy (SEM), atomic force microscopy (AFM), UV-visible absorption spectroscopy, Raman spectroscopy and x-ray photoemission spectroscopy (XPS) were used to characterize the ZnO films before and after the interactions with the biofilm and the ultraviolet light, respectively. The as-deposited film was highly textured with the wurtzite (0002) in-plane orientation (c-axis perpendicular to ZnO surface) and had a surface rms roughness of 49.7 nm. In the as-deposited film, the Zn to O ratio was 1 to 0.95. After the UV and biofilm treatments, the ZnO film surface had become rougher (rms roughness 68.1 nm) and presented uniform micron-sized pitting randomly distributed, while the zinc to oxygen ratio had become 1 to 2.2. In this case, both the UV-visible and Raman spectra pointed to degradation of the structural quality of the material. On the strength of these data, we propose a model for the mediation of the bactericidal activity in which the photogeneration of highly oxidizing species and the presence of active surface defect sites both play an important role. This study is of particular interest for the acute problem of disinfection of pathogenic biofilms which form on medical device/implant surfaces.

“…The majority of available reports on photocatalytic paper mention TiO 2 as a photocatalyst, which absorbs light mostly in the ultraviolet region of the electromagnetic spectrum [7]. Ghule et al [14] reported the growth of ZnO nanoparticulate coating on paper support and studied its antibacterial property. ZnO nanorods, which can be strongly attached to any type of substrates through proper surface treatment before seeding [15], are an attractive option for photocatalytic applications.…”

Zinc oxide (ZnO) nanorods were grown on a paper support prepared from soft wood pulp. The photocatalytic activity of a sheet of paper with ZnO nanorods embedded in its porous matrix has been studied. ZnO nanorods were firmly attached to cellulose fibers and the photocatalytic paper samples were reused several times with nominal decrease in efficiency. Photodegradation of up to 93% was observed for methylene blue in the presence of paper filled with ZnO nanorods upon irradiation with visible light at 963 Wm -2 for 120 min. Under similar conditions, photodegradation of approximately 35% was observed for methyl orange. Antibacterial tests revealed that the photocatalytic paper inhibits the growth of Escherichia coli under room lighting conditions.

“…Gedanken and Ghule and their coworkers reported that the ZnO and cellulose can adhere to each other by hydrogen bonds (Ghule et al 2006;Perelshtein et al 2009). Since the nanocellulose carries a negative charge and the ZnO crystal has a polar plane, we propose that the formation mechanism of ZnO is associated with the behaviors of ZnO crystal growth.…”

“…Many studies reported preparation of ZnO/cellulose composite (Ghule et al 2006;Perelshtein et al 2009). Previously, microcrystalline cellulose (MCC) was applied to synthesize ZnO, yielding a product with good photocatalytic performance (Zuo et al 2014).…”

*Well-crystallized and hexagonal wurtzite ZnO was synthesized with nanocellulose using a facile hydrothermal method. Many highly active (001) facets were retained in the obtained ZnO nanocrystals, presumably due to interaction between the polar facet of ZnO and the nanocellulose. Given its effective surface area, the synthesized ZnO exhibited good photocatalytic activity of degrading methylene blue. Its degradation efficiency reached 94.4% within 30 min (UV irradiation power of 6 W), which was 34% higher than that of Degussa TiO2 P25. The ZnO photocatalyst also exhibited excellent reusability, confirmed by no obvious abatement after its being re-used for 8 cycles. These ZnO nanomaterials were synthesized using renewable nanocellulose derived from cotton. This environmentally friendly and cost-effective approach is anticipated to be applied in the future synthesis of small-sized ZnO photocatalysts.
