The production of ROS has been concerned in the onset and development of many diseases (such as cancer, atherosclerosis, diabetes, and neurodegeneration). Sci. Klabunde, Metal oxide nanoparticles as bactericidal agents. Prog. Wang, J. 3(1), 95–101 (2007). 2019 Oct;103:109840. doi: 10.1016/j.msec.2019.109840. Alivov, C. Liu, A. Teke, M. Reshchikov, S. Dogan, V. Avrutin, S.J. These characteristics enable ZnO to have remarkable applications in diverse fields . NPs penetrate through holes, pits or protrusions in the cell wall. Int. Particular emphasize was given to bactericidal and bacteriostatic mechanisms with focus on generation of reactive oxygen species (ROS) including hydrogen peroxide (H2O2), OH− (hydroxyl radicals), and O2 5a–c. These new materials with improved antimicrobial properties permit also tracking of food during storage and transfer. Finally, Wang et al. Lu, Zinc oxide nanostructures: synthesis and properties. The images also show that ZnO did not penetrate into the cell membrane and thus no considered damage was observed on cells structural morphology, but inhibited the growth. doi:10.1371/journal.pone.0111289, W. Song, J. Zhang, J. Guo, J. Zhang, F. Ding, L. Li, Z. 12(6), 449–457 (2001). Their findings revealed as well wide spectrum of antimicrobial activities of ZnO-NPs against various doi:10.1021/es9030497, W. Jiang, H. Mashayekhi, B. Xing, Bacterial toxicity comparison between nano- and micro-scaled oxide particles. FEMS Microbiol. doi:10.1006/scdb.2001.0282, N. Talebian, S.M. The inhibition accounts for variations in cell physiology, cell wall constitution, and the metabolism [93, 94]. The larger the surface area and the higher concentration of oxygen species on the surface can obtain greater antibacterial activity by smaller particles, which was in contrast to that of Franklin et al. In case of E. coli O157:H7 (a major foodborne pathogen) showed 100 % growth inhibition in the presence of a ZnO concentration which is approximately 8–32 times that used for C. jejuni. 2b).

Hu, Polymorphous ZnO complex architectures: selective synthesis, mechanism, surface area and Zn-polar plane-codetermining antibacterial activity. C 112(31), 11859–11864 (2008). Grisham, G.E. Kim, J.Y. ZnO-NPs in aqueous solution under UV radiation have phototoxic effect that can produce ROS such as hydrogen peroxide (H2O2) and superoxide ions (O2−). Surf. Investigations on antibacterial nanomaterials, mostly ZnO-NPs, would enhance the research area of nanomaterials, and the mechanisms and phenomenon behind nanostructured materials. This composition contributes in the electrical conductivity of the cellular structure. Peng et al. Issues of aggregation, re-precipitation, settling, or non-dissolution impede the synthesis processes. Nano-sized ZnO exhibits varying morphologies and shows significant antibacterial activity over a wide spectrum of bacterial species explored by a large body of researchers [5, 7–13]. These crystal structures are illustrated in (Fig. Seil, T.J. Webster, Antimicrobial applications of nanotechnology: methods and literature. S. aureus is well known of causing contamination in hospital implants leading to serious infections . It was suggested that photo-excitation caused desorption of the oxygen molecules from the surface, thus the surface potential decreased and underlying photoconductivity of ZnO. The OD should serially be monitored hourly up to 12 h of incubation, and finally after 24 h of overnight incubation for the determination of the percentage of growth inhibition . One of these essential applications is in food industry; as an antibacterial agent in food packaging and towards foodborne pathogen. Ceram. doi:10.1074/jbc.274.15.10119, L. Yuan, Y. Wang, J. Wang, H. Xiao, X. Liu, Additive effect of zinc oxide nanoparticles and isoorientin on apoptosis in human hepatoma cell line. Bao, Z. Su, R. Gurwitz, F. Capasso, X. Wang, Z. Ren, Photoinduced oxygen release and persistent photoconductivity in ZnO nanowires. Therefore, solubilized low concentrations Zn2+ can induce a comparatively high tolerance in bacteria. J. This might be probably suggested that the size of the particles did not allow their penetration into the cell wall and membrane.  found that the action of ZnO-NPs on C. jejuni has stimulated morphology disorder, intracellular components outflow, and considerable release in gene expression of oxidative stress of C. jejuni. Clipboard, Search History, and several other advanced features are temporarily unavailable. The results illustrated in Fig. The dissolution of ZnO-NPs into Zn2+ was reported as size dependent, and few studies suggested this dissolution of Zn2+ responsible for toxicity of ZnO-NPs. 210–218, M. Ramani, S. Ponnusamy, C. Muthamizhchelvan, From zinc oxide nanoparticles to microflowers: a study of growth kinetics and biocidal activity. Both phase and atomic structures confirmed the polycrystalline arrangement of ZnO nanoparticles.  also attributed the disruption of the cell membrane to peroxidation of the unsaturated phospholipids as a result of photocatalytic prompted H2O2.

Res. 73(6), 1712–1720 (2007). They emerged with the result that ZnO-NPs have strong antibacterial activity toward these human pathogens.
