To confirm the dominant role of ROS-mediated antibacterial activity, a zinc ion leaching study was also carried out, and the authors report that Zn2+contribute minimally to the antibacterial activity. Concepción García-GómezMaria Dolores Fernández, in Comprehensive Analytical Chemistry, 2019. 4. nanoparticle zinc oxide regulations 4.1 europe 4.2 united states 4.3 asia-pacific. Moreover, it has been reported that more than 95% inhibition of S. aureus growth could be seen at a ZnO nanoparticle concentration of ≥1 or 1 mM, whereas complete inhibition of E. coli growth was observed with ≥3 mM of ZnO nanoparticle concentrations (Brayner et al., 2006; Reddy et al., 2007; Jones et al., 2008; Liu et al., 2009). Studies conducted by Liu et al. However, no clear differences are observed between the effects on plants by ZnO bulk or NPs, perhaps because the effects of ZnO NPs cannot be established based on solubility alone. The dissolved metal ions were incorporated into blend films of CS and PVA with different concentrations of polyoxyethylene sorbitan monooleate and Tween 80 (T80). Figure 5.9 shows the thermogravimetric analysis/differential thermal analysis (TGA/DTA) curves in nitrogen for the precursor (sample Z1). The UV–Vis transmittance spectra of epoxy and nanocomposites at the 0.07 wt% ZnO are shown in Fig. The important biomedical applications of zinc oxide nanoparticles are listed as below:- 1. Another theory that has been used to explain shape-dependent antimicrobial activity involves a correlation between enhanced ZnO NP specific surface area and higher bacterial toxicity [137], which is again relates to a direct contact-based antibacterial mechanism. Therefore, the reviewed literature indicated that ZnO nanoparticles or functionalized ZnO nanoparticles have extensive biological applications and benefits. The opinions expressed here are the views of the writer and do not necessarily reflect the views and opinions of AZoNano.com. Surface coating or modification of ZnO nanomaterials by doping it with another metal ion is one of most advanced and intriguing approaches to increase their affinity or activity to improve their applicability (Cioffi and Rai, 2012). We studied the safety of repeated application of agglomerated zinc oxide (ZnO) NPs applied to human volunteers over 5 days by assessing the skin penetration of intact ZnO-NPs and zinc ions and measuring local skin toxicity. This study was conducted to investigate effects of dietary zinc oxide nanoparticles (nano-ZnOs) on growth, diarrhea rate, mineral deposition (Zn, Fe, and Mn), intestinal morphology, and barrier of weaned piglets. The data obtained led the authors to conclude that ROS-induced oxidative stress could not be the primary mechanism of antibacterial activity of the ZnO NPs studied, at least with respect to MRSA. ZnO NPs also possess high catalytic and photochemical activities, with high optical absorption in the UVA (315–400 nm) and UVB (280–315 nm) regions which is beneficial with respect to induced bacterial toxicity [124]. The zinc oxide nanoparticles are commonly used in cosmetics industry like sun screen lotions due to its UV purifying properties (Wodka et al., 2010).The zinc oxide nanoparticles has wide range of biomedical applications. It is also observed that the endothermic peak occurs at 253.85 °C, indicating the transformation of the precursor to ZnO crystal. Some of the synonyms used for ZnOs are oxydatum, zinci oxicum, permanent white, ketozinc and oxozinc. Alessandra Nara de Souza Rastelli, ... Michel R. Hamblin, in Nanobiomaterials in Dentistry, 2016. The formed ZnO-NPs were characterized by UV–Vis spectroscopy, Fourier transform infrared (FT-IR), transmission electron microscopy (TEM), energy … ZnO nanoparticles also have antibacterial effects when incorporated in composite resins (Hojati et al., 2013; Sevinç and Hanley, 2010). [191] described that ZnO NPs penetrate the bacterial cell envelope and disorganize the cell membrane. Not only the sizes of ZnO NPs, but also its different shapes show varying antimicrobial activity. Some studies indicate that nanoparticles in large doses can harm living cells and organs. Table 5.1. Interestingly, smaller ZnO NPs produce increased amounts of H2O2 due to higher density and surface-to-volume ratio (Brayner et al., 2006). alginate was reported by Baskoutas et al. Sometimes ZnO NPs dissociate to Zn2+ ions which can diffuse through damaged cell membrane and interact with intracellular contents (Brayner et al., 2006). MashitahMat Don , ... JasonJeevanandam , in Nanobiomaterials in Antimicrobial Therapy, 2016. Zinc oxide nanoparticles (ZnO NPs) are of particular interest for antimicrobial applications as, unlike many other types of NPs, ZnO is an FDA approved food additive and is generally recognised as safe and non-toxic in low concentrations. In the past two decades, ZnO NPs have become one of the most popular metal oxide nanoparticles in biological applications due to their excellent biocompatibility, economic, and low toxicity. The released particles were very active against marine biofouling strains, Chlamydomonas sp. 5.11. These activities are associated with the ability of ZnO NPs to generate reactive oxygen species (ROS) and induce apoptosis. ZnO Zinc oxide nanoparticles Particular Materials Our Zinc Oxide (ZnO) nanoparticles portfolio consist of particles with diameters ranging from 16 to 40 nanometers and find applications in several industries. It has long been reported that the antibacterial activity of ZnO NPs is critically dependent on NP size, with higher antimicrobial activity commonly detected for smaller particles [131]; several explanations for this have been proposed and thoroughly investigated by many groups, though a consensus has yet to be reached. 5.9. Although ZnO NPs are highly toxic compared to other metal oxide NPs, they are used in different fields as antimicrobials due to their high stability under harsh processing conditions (Stoimenov et al., 2002). Many studies have shown that ZnO nanoparticles have selective toxicity to bacteria and only exhibited minimal effect on human cells (Brayner et al., 2006; Reddy et al., 2007; Zhang et al., 2007). Biological methods are relatively new and may employ plant extracts and other microorganisms. The ZnO crystallite sizes are calculated using Scherrer’s formula (D = κλ/(βcosθ)) and the results are given in Table 5.1. The technology is designed for individual nanoparticle coating and as such prevents the formation of … ZnO NPs were synthesized by the Pechini method by reacting CA with ethylene glycol. Green synthesis of nanoparticles by biological systems especially plant extracts has become an emerging field in nanotechnology. 5.11. ZnO nanoparticles in the size range from 2 to 7 nm were prepared by addition of LiOH to an ethanolic zinc acetate solution. Concurrently, nanomaterials containing zinc, in particular zinc oxide nanoparticles (ZnO NPs), are becoming increasingly attractive as innovative agents for medical applications. Copyright © 2021 Elsevier B.V. or its licensors or contributors. (2014) administrated ZnONPs to Sprague–Dawley rats through intratracheal inhalation and after 24 h of treatment they declared that NPs agglomerated especially in the lungs and insignificant levels of zinc were observed in the heart, liver, kidneys, and blood. That is the reason why ZnO is particularly active in cell wall damage, increasing membrane permeability, internalization of NPs due to loss of proton motive force. Gurpreet Singh Dhillon, ... Satinder Kaur Brar, in Comprehensive Analytical Chemistry, 2012. 6. nanoparticle zinc oxide swot analysis. (2011) investigated the antimicrobial activity of ZnO nanoparticles against E. coli and S. aureus and evaluated the effects of concentration and particle size reduction on the antibacterial activity of ZnO nanoparticles. Owned and operated by AZoNetwork, © 2000-2021. The synthesized sample was calcined at different temperatures for 2 h. The samples were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS), and proton-induced X-ray emission (PIXE) … Overall, published reports clearly suggest that ZnO nanoparticles have significantly higher antibacterial or antifungal activity compared to the bulk ZnO. We use cookies to enhance your experience. ZnO-NPs exhibit attractive antibacterial properties due to increased specific surface area … Zinc oxide nanoparticles (ZnONPs) were investigated for their great antimicrobial effect against multiple foodborne pathogens and food contaminants, as for example enterotoxigenic E. coli, Botrytis cinerea, and Penicillium expansum. More info. Due to its high solubility in water, the application of ZnO NPs in water treatment is, however, debated due to sensitivity of aquatic organisms towards ZnO [193]. This method [Spanhel, L.; Anderson, M. A. J. Studies have revealed that ZnO nanoparticles have strong ROS generating potential. A smaller but significant inhibition of biofilm in the material containing only 5% ZnO nanoparticles was shown. Among our customers we find personal care products&cosmetics, electronics, coating and tiles industry. Another reason for ZnO NPs’ pronounced antimicrobial activity is their high surface to volume ratio and surface abrasiveness. ZnO nanopowders are available as powders and dispersions. Anyaogu and co-workers [198] functionalized the copper NPs with an acrylic group to copolymerize with other acrylic monomers. PCC 7002 (marine) and Phaeodactylum tricornutum CCMP 1327. In order to determine whether ZnONPs produce any cardiopulmonary harmful effects, Chuang et al. The presence of phosphates and/or organic components in the PBS, MD and LB media caused a decrease in the concentration of free/labile Zn2+ ions, and therefore decreased toxicity. Additionally, zinc oxide nanoparticles were used in … They exhibit antibacterial, anti-corrosive, antifungal and UV filtering properties. This article provides further detail on the properties and applications of zinc oxide nanoparticles (ZnO). PCC 6803 (freshwater), Synechococcus sp. (2013) evaluated the ability of a flowable resin, containing 1%, 2%, 3%, 4%, and 5% by weight of ZnO nanoparticles with an average diameter of 20 nm, to inhibit S. mutans. Hojati et al. Cristina Ş. Iosub, ... Ecaterina Andronescu, in Nanostructures for Novel Therapy, 2017. Zinc oxide nanoparticles can enhance the antibacterial activity of ciprofloxacin. To reduce the opaque appearance of zinc oxide, many sunscreen companies are making the particle smaller through a process referred to as “micronizing” to produce nanosized zinc particles. The morphology of ZnO NPs is also expected to affect their antimicrobial activity, and this has been demonstrated experimentally (Table 2), though the underlying cause of shape-dependent antibacterial action is still under active investigation. ZnO is used in pharmaceutical products, such as antibacterial cream, lotions and ointments, and in surface coatings to prevent biofilm formation [192]. The use of ZnO NPs as a fertiliser has the advantages of slow Zn release, which results in not only less ion loss in relation to Zn salt, but also increased Zn availability in relation to bulk ZnO during plant growth. Most significant weight loss occurs in the temperature range of 190–260 °C. Other mechanisms that have been reported in the literature such as (a) deactivation of enzymatic activity of the bacterial respiratory chain; (b) changes in bacterial structure caused by the nanoparticles; and (c) interaction with bacterial DNA, etc. They exhibit antibacterial, anti-corrosive, antifungal and UV filtering properties. % in H 2 O ZnO pricing Regardless of their source, however, zinc ions have been described to lead to bacterial cell death through direct membrane interaction leading to membrane destabilisation and increased permeability [129], and through binding with nucleic acids and enzymes of the respiratory system, leading to disruption of enzyme function [130]. There are also other studies confirming the strong antimicrobial activity of ZnO nanoparticles wherein the nanoparticles could completely lyse the foodborne bacteria Salmonella typhimurium (Liu et al., 2009). ROS, Zn2+) at a faster rate due to the increase in surface area-to-volume ratio with decreased particle size. Taken together, and considering that the authors ruled out the possibility that zinc ions were the cause of ZnO-induced antibacterial activity, it was proposed that the particles penetrate the cell membrane, which is followed by ROS-triggered oxidation of the cellular contents leading to cell death. This synthesis involves particle growth at … Transparency of ZnO/epoxy nanocomposite samples with the 0.07 wt% ZnO nanoparticles prepared at different temperatures (Li et al., 2006). Bryce P. Nelson,1* Pengjie Shi,1 Wei Wei,1 Sai-Wing Tsang2 and Franky So3 1MilliporeSigma, 6000 N. Teutonia Ave., Milwaukee, WI, USA 53209 2Sai-Wing Tsang, Department of … At low doses, although ZnO NPs enhance crop growth in biomass and yield terms, the extent of the effects is conditioned by plant species and soil characteristics. Upon light irradiation, ZnO NPs can be excited and react with O2 to generate ROS; ROS production has been widely reported as a contributing factor to the antimicrobial action induced by ZnO NPs [31], but this explanation is particularly controversial. Zinc oxide nanoparticles (ZnO NPs) are used in an increasing number of industrial products such as rubber, paint, coating, and cosmetics. They are used widely in the food industry to preserve colors and prevent spoilage through their antimicrobial activity. Nanoparticle zinc oxide, ZnO, is a form of zinc oxide where the compound is formed into individual particles as small as 20 nanometers in diameter. In vitro results showed that ZnO NPs displayed more toxic effects than the other NPs, especially according to WST-8 and LDH assays, whereas in vivo NPs generated oxidative damages to the lungs and thus induced immunotoxicity. The NPs became an integral part of the polymer backbone which slowed down particle release rate from the polymer matrix. The antimicrobial activity of nano-CuO is not known; however properties, such as extremely high surface areas and unusual crystal morphologies may render CuO as potential antimicrobial agents [195]. From: Comprehensive Nanoscience and Nanotechnology (Second Edition), 2019, Mohammad A. Mokammel, ... Saleem Hashmi, in Reference Module in Materials Science and Materials Engineering, 2019. The antibacterial activity of a resin containing 10% by weight of ZnO nanoparticles was investigated by Sevinç and Hanley (2010). As the particle size increases, the transmittance of UV light generally decreases. Zinc oxide is a widely used broad-spectrum sunscreen, but concerns have been raised about the safety of its nanoparticle (NP) form. S.-Y. In addition, ZnO NPs are toxic to meticillin-resistant bacteria such as Streptococcus agalactiae (Gram-positive) and S. aureus by increasing permeability via confusion inside the cell membrane. The synthesis of very small ZnO nuclei was simplified. Natural Product-Based Fabrication of Zinc-Oxide Nanoparticles and Their Applications. Moreover, the mechanical properties of dental adhesives and composite resins after inclusion of ZnO nanoparticle fillers were not adversely affected (Chen et al., 2012; Ferracane, 2011). Fu, in Physical Properties and Applications of Polymer Nanocomposites, 2010. Synthesis of zinc oxide (ZnO) nanoparticles is first introduced since ZnO is an effective UV filter which will be used for preparation of UV shielding epoxy nanocomposites. Soc. Xie et al. In this study, zinc oxide nanoparticles were synthesized using Laurus nobilis L. leaves aqueous extract and two different zinc salts (zinc acetate and zinc nitrate) as … These films effectively killed S. aureus [194]. Furthermore, the extent of Zn2+ dissolution upon ZnO NP dispersion depends on the nature of the surrounding medium (e.g. Inverted Organic Photovoltaic Devices Using Zinc Oxide Nanocomposites as Electron Transporting Layer Materials. Biofilm growth was reduced 80% in comparison to the unmodified resin. On the other side, Adamcakova-Dodd et al. The capabilities of a scanning transmission electron microscopy detector, Coxem’s STEM Module, are detailed on this page. However, it can be seen from Fig. They found that only resins containing 4% or 5% nanoparticles showed biofilm inhibition, and after 1 week, the effect of nanoparticles was no longer observed for any of the materials. The contact or accumulation of ZnO NPs at the cell surface can cause morphology changes and increased permeability within the immediate membrane contact area, lead to an increased dissolution of Zn2+ ions, and/or facilitate release ROS release directly at the bacterial surface [132,134,135]. 1991, 113, 2826] was modified and extended at several points. This team performed a comprehensive series of experiments to evaluate the extent of oxidative stress initiated by ZnO NPs compared to H2O2, which is known to impart ROS-mediated antimicrobial activity. Badal Kumar Mandal, in Nanobiomaterials in Antimicrobial Therapy, 2016. Copper-hydrotalcite (Cu-HT) can be used as an alternative disinfectant to chlorine in a water-purification system. This article provides further detail on the properties and applications of zinc oxide nanoparticles (ZnO). Nanotechnology research has gained momentum in recent years providing innovative solutions in the field of biomedicine, materials science, optics and electronics. (2014) evaluated the antibacterial properties of a flowable composite resin containing 1% Ag and ZnO nanoparticles on S. mutans and Lactobacillus spp. A synergistic effect existed between CuO NPs and sub-minimum bacteriocidal concentrations of AgNPs. In a very recent paper, Kadiyala et al. In this work, uncoated, hexagonal pyramid-shaped ZnO NPs were synthesised and spherical ZnO NPs were obtained commercially; the ROS-generating potential of these samples was assessed, as was their antimicrobial efficacy against methicillin resistant Staphylococcus aureus (MRSA). ZnO NPs have shown substantial antimicrobial activity against common food pathogens such as Campylobacter jejuni, E. coli O157:H7, Salmonella spp., Listeria monocytogenes, and S. aureus indicating its usefulness as a food preservative. (2014) showed that the titanium-doped ZnO powders synthesized from different zinc salts had antibacterial action against E. coli and S. aureus. The modified resin significantly inhibited biofilm formation by S. sobrinus, one of the main bacteria causing caries. Zinc is a Block D, Period 4 element, while Oxygen is a Block P, Period 2 element. Copper oxide (CuO) is less costly as compared to silver and show chemical and physical stability when mixed with polymers. Controlled release did not affect antimicrobial activity of copper NPs and correlated well with conventional copper-based biocides. For instance, some authors have proposed that ZnO nanorods have a higher potential to impart nanomechanical stress-induced toxicity to Gram-negative bacteria than do spherical ZnO NPs [34], while other authors have reported that 1-D ZnO nanostructures have enhanced ability to penetrate bacterial cell membranes compared to spherical ZnO NPs [136].
