zinc oxide nanoparticles review

The efficiency of ZnO-NPs against Salmonella was also tested at lower concentration. Abstract. C 119(3), 1433–1441 (2015). doi:10.1021/ja056428l, A. Lipovsky, Z. Tzitrinovich, H. Friedmann, G. Applerot, A. Gedanken, R. Lubart, EPR study of visible light-induced ROS generation by nanoparticles of ZnO. The transparent particles, which effectively filter out ultraviolet-a (UVA) and ultraviolet-b (UVB) light, are then coated with inert silicon or aluminum oxide layers and tend to clump together into groups that are 200 to 500 nanometers in diameter. Antibacterial activity of zinc oxide nanoparticles (ZnO-NPs) has received significant interest worldwide particularly by the implementation of nanotechnology to synthesize particles in the nanometer region. 95–128. Surface defects strongly affect the toxicity of ZnO. J. In spite of its simple chemical formula, ZnO has very rich defect chemistry [96], which is associated with its antimicrobial activity. Briefly, an agar diffusion test was performed by inoculating the targeted bacteria (E. coli and S. aureus) on NA using ZnO-NPs at a defined concentration range. In addition to its unique antibacterial and antifungal properties, ZnO-NPs possess high catalytic and high photochemical activities. doi:10.1002/jbm.a.30789, J.T. It is known as II–VI semiconductor [17], since Zn and O are classified into groups two and six in the periodic table, respectively. Leung et al. Int. Further discussions are in Sect. PubMed Google Scholar. The intrinsic properties of metal NPs such as zinc oxide (ZnO), TiO2, and silver are mostly characterized by their size, composition, crystallinity, and morphology. Moreover, isotherms confirmed the mesoporous structure of all ZnO nanoparticles with superior specific surface area and porosity volume. As announced by the Food Standards Agency, which is a program Limbach, A. Bruinink, W.J. Interestingly, ZnO-NPs are reported by several studies as non-toxic to human cells [14], this aspect necessitated their usage as antibacterial agents, noxious to microorganisms, and hold good biocompatibility to human cells [12]. This phenomenon induced the generation of ROS from ZnO surface, as described earlier. Bacteria are generally characterized by a cell membrane, cell wall, and cytoplasm. These crystal structures are illustrated in (Fig. MIC was determined by the lowest concentration of each NPs, which inhibited the growth. It was found to exhibit higher antibacterial activities to E. coli under visible light or in the dark. doi:10.1016/j.tifs.2011.01.001, C. Silvestre, D. Duraccio, S. Cimmino, Food packaging based on polymer nanomaterials. Med. doi:10.1016/j.nano.2010.10.001, J. Sawai, Quantitative evaluation of antibacterial activities of metallic oxide powders (ZnO, MgO and CaO) by conductimetric assay. Such consistent results give a sign of possibly further mechanisms so far to be determined to produce reactive species without illumination and in dark. While other researchers used appropriate capping agents [12] or deflocculants (sodium silicate Na2SiO3 or sodium carbonate Na2CO3). The importance and significance of ZnO-NPs in various areas has developed global interest to study their antibacterial activity. In general, a correspondence between NPs size and bacteria appears to be required for the bioactivity of ZnO-NPs, as well the concentration. 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. 72(12), 126501 (2009). Nanotechnology is a research hot spot in modern materials science. a NPs internalization into the cell and translocation. doi:10.1116/1.2815690, J.W. Also, Wang et al. Biol. Techniques of doping and implanting foreign metals on ZnO nanostructures to develop functional antibacterial agent have become a topic among researchers. Van de Walle, Fundamentals of zinc oxide as a semiconductor. by A. Méndez-Vilas (Formatex, Badajoz, 2011), pp. 2019 Dec;201:111624. doi: 10.1016/j.jphotobiol.2019.111624. This was attributed to the increased reactivity of small size NPs, as the generated amount of H2O2 is significantly dependent on the surface area of ZnO-NPs [12]. The toxicity of these species involves the destruction of cellular components such as lipids, DNA, and proteins, as a result of their internalization into the bacteria cell membrane. The bactericidal activity of ZnO-NPs (8–10 nm size) against E. coli DH5α and S. aureus was examined and found to be effective at 80 and 100 µg mL−1. Reddy et al. This current review aimed to discuss and analyze research works that addressed the potential use of ZnO-NPs for antibacterial activity. Bell, D.G. Song, Piezoelectric nanogenerators based on zinc oxide nanowire arrays. The effect of the pH value of the reaction medium in the antibacterial activity mechanism has been considered. Langmuir 27(7), 4020–4028 (2011). 98(4), 041301 (2005). Yamamoto [51] found that the higher concentration and the larger surface area can obtain the better antibacterial activity. The two main issues considered in this review are the evidence for the ability of these NPs to penetrate the skin to reach viable cells and the potential toxicity exerted by them.
