Wilson, A.T. Abraham, M. Sevanan, Synthesis, characterization, and antimicrobial activity of zinc oxide nanoparticles against human pathogens. Eng. Additionally, a brief presentation of a study conducted by authors of this review was explored. J. Nanomed. doi:10.1016/j.tifs.2012.11.006, N. Soares, C.A.S. Their results showed bacteriostatic action towards E. coli, which increased at higher ZnO-NPs concentrations and reduced size. TiO2 and TiO2–Ag antimicrobial thin films, in 2011 International Conference on Nanoscience, Technology and Societal Implications (NSTSI), Bhubaneswar, USA, 8–10 December 2011 (IEEE, 2011), pp. Irwin, T. Jin, X. Shi, Antibacterial activity and mechanism of action of zinc oxide nanoparticles against Campylobacter jejuni. For example, infections by Shigella flexneri cause 1.5 million deaths annually, due to contaminated food and drinks by these bacteria [16]. Thin Solid Films 516(12), 3893–3898 (2008). Generally, it has been observed from the intensive studies held, that the antibacterial activity of ZnO can be verified under UV light as well as in the dark to inhibit the bacterial growth. have resulted in a rapid increase of titania and zinc oxide in sunscreens. J. Biomed. Rod-structures of ZnO have (111) and (100) facets, whereas spherical nanostructures mainly have (100) facets. doi:10.1016/j.materresbull.2006.11.035, J. Zhang, L. Sun, J. Yin, H. Su, C. Liao, C. Yan, Control of ZnO morphology via a simple solution route. Langmuir 24(8), 4140–4144 (2008). The mechanism of antibacterial activity by ROS generation due to treatment with ZnO-NPs using DCFH-DA dye was studied by Dwivedi et al. There is a strong trend that considers two mechanisms underlying the interaction of NPs with bacteria, to be mainly concerned [13]: (i) excessive ROS generation, mostly hydroxyl radicals (HO•) and singlet oxygen (1O2) [60, 80, 126, 127], and (ii) NPs precipitation on the bacterial exterior; or NPs gather in the cytoplasmic area or in the periplasm space, thus, disrupt the cellular activities, resulting in membranes disturbance and disorder [7, 40]. The importance and significance of ZnO-NPs in various areas has developed global interest to study their antibacterial activity. microorganisms (Table 2). 3g). ZnO-NPs concentrations that are 20–100 times were required for decreasing 1–2 logs of cells viability. Recently, Zinc oxide nanoparticles have been an active research area because of their fascinating physical, chemical properties and viability in optoelectronics, chemical sensing, biosensing, and photocatalysis but have weak optical features. Size-dependent bactericidal activity was also extensively evaluated by Raghupathi et al. The photocatalysis is described as a photo-induced oxidation process that can damage and inactivate organisms [67]. Defects extensively change grain boundary properties and the IV characteristics [23]. Colloids Surf. Zinc Oxide Nanoparticle as a Novel Class of Antifungal Agents: Current Advances and Future Perspectives. Increased outbreaks and infections of pathogenic strains, bacterial antibiotic resistance, emergence of new bacterial mutations, lack of suitable vaccine in underdeveloped countries, and hospital-associated infections, are global health hazard to human, particularly in children. It was attributed to membrane disruption and raises its permeability, which in turn causes the gathering of ZnO-NPs inside the membrane and then reaches the cytoplasm. 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. doi:10.1002/jbm.a.30789, J.T. 40(14), 4374–4381 (2006). doi:10.1371/journal.pone.0085981, G. Colon, B.C. It is considered as the synthesis, characterization, and exploration of materials in the nanometer region (1-100 nm). Int. Environ. Nel, Comparison of the mechanism of toxicity of zinc oxide and cerium oxide nanoparticles based on dissolution and oxidative stress properties. Yamamoto [51] found that the higher concentration and the larger surface area can obtain the better antibacterial activity. Many studies have reported that the toxicity is significantly affected by the various morphologies of ZnO-NPs [36, 77, 78]. doi:10.1016/j.tiv.2012.12.001, R. Wahab, N.K. Thus, these species are found on the outer surface of the bacteria, by contrast, H2O2 molecules are able to pass through the bacterial cell wall, subsequently leading to injuries and destroy, and finally triggering cell death [40, 88]. Semin. Nat. NPs penetrate through holes, pits or protrusions in the cell wall. It was elucidated on the fact that smaller surface curvature of sphere causes high equilibrium solubility.

Green technology (biosynthesis) is playing a vital role in the synthesis of nanoparticles due to low cost, non-toxicity and other environmental advantages. 41(24), 8484–8490 (2007). c Nano Lett.
