“…However, it decreased slightly in 0.05 mgmL −1 CuONPs indicating its toxic nature. According to Nair et al [39] seed germination percentage of Vigna radiata becomes significantly reduced due to toxic effects of CuONPs which was observed in our case also. Furthermore, root length was increased in CuONPs (0.025 mgmL −1 ) treated seedlings compared to control (Table 1).…”

“…Furthermore, root length was increased in CuONPs (0.025 mgmL −1 ) treated seedlings compared to control ( Table 1). Retardation of primary root growth ( Figure 10) was observed upon exposure to higher concentrations of CuONPs (0.05 mgmL −1 ) as it was observed by Nair et al [39].…”

“…Morphological and topographical characterization of the nanoparticles had been well established by the electron microscopic studies [39]. On a carbon coated copper grid thin films of the synthesized nanoparticles were prepared (30 × 30 µm mesh size) and a drop of the nanoparticle suspension was spotted on the grid.…”

Biosynthesis of copper oxide nanoparticles (CuONPs) in a cost-effective and eco-friendly way has gained its importance. CuONPs has been prepared from copper sulfate by using Adiantum lunulatum whole plant extract. CuONPs have been characterized by X-ray diffraction, Fourier transform infrared spectroscopic, transmission electron microscope, etc. Mono-disperse, spherical, pure, and highly stable CuONPs have formed with an average diameter of 6.5 ± 1.5 nm. Biosynthesized CuONPs at different concentrations were applied to seeds of Lens culinaris. Physiological characteristics were investigated in the germinated seeds. Roots obtained from the seeds treated with 0.025 mgmL−1 concentration of CuONPs showed highest activity of different defence enzymes and total phenolics. However, at higher concentration it becomes close to control. It showed gradual increase of antioxidative enzymes, in accordance with the increasing dose of CuONPs. Likewise, lipid peroxidation and proline content gradually increased with the increasing concentration. Reactive oxygen species and nitric oxide generation was also altered due to CuONPs treatment indicating stress signal transduction. Finally, this study provides a new approach of the production of valuable CuONPs, is a unique, economical, and handy tool for large scale saleable production which can also be used as a potent plant defence booster instead of other commercial uses.

“…Begum and Fugetsu reported that multi-walled carbon nanotubes (MWCNTs) of 20, 200, 1000, and 2000 mg/L were phytotoxic to red spinach, lettuce, rice, and cucumber, and the shoot and root weights were dramatically decreased with increasing nanotube concentrations [12]. Nair et al showed that the phenotype of mung bean was regulated by media containing copper oxide nanoparticles of 20, 50, 100, 200, and 500 mg/L, and the reactive oxygen species generation in the roots increased gradually with the increase of the nanoparticle concentration [13]. In addition, nanomaterials, such as graphene, CNTs, and copper oxide nanoparticles, have been shown to be cytotoxic to various crops [14][15][16][17].…”

The control and promotion of plant and crop growth are important challenges globally. In this study, we have developed a nanomaterial-assisted bionic strategy for accelerating plant growth. Although nanomaterials have been shown to be toxic to plants, we demonstrate herein that graphene oxide can be used as a regulator tool for enhancing plant growth and stability. Graphene oxide was added to the growth medium of Arabidopsis thaliana L. as well as injected into the stem of the watermelon plant. We showed that with an appropriate amount provided, graphene oxide had a positive effect on plant growth in terms of increasing the length of roots, the area of leaves, the number of leaves, and the formation of flower buds. In addition, graphene oxide affected the watermelon ripeness, increasing the perimeter and sugar content of the fruit. We believe that graphene oxide may be used as a strategy for enabling the acceleration of both plant growth and the fruit ripening process.

“…These ENPs are also active against natural enemies of the mosquito, suggesting a potential public health problem through disruption of biological control of mosquito populations [64]. There is evidence that CuO-based ENPs are toxic to the reproduction of Enchytraeus crypticus (earthworm) and this may alter soil processes, since earthworms are key players in soil health [75]. Soil processes may also be altered via the nitrogen cycle in plants when impacted by TiO 2 , as well as by Agbased and CuO ENPs.…”

Antimicrobial engineered nanoparticles in the built cultural heritage context and their ecotoxicological impact on animals and plants: a brief review

et al. 2018

Nanoparticles (NPs) of metal oxides, sometimes referred to as engineered nanoparticles have been used to protect building surfaces against biofilm formation for many years, but their history in the Cultural Heritage world is rather short. Their first reported use was in 2010. Thereafter, a wealth of reports can be found in the literature, with Ti, Ag and Zn oxides being the major protagonists. As with all surface treatments, NPs can be leached into the surrounding environment, leading to potential ecotoxicity in soil and water and associated biota. Dissolution into metal ions is usually stated to be the main mode of toxic action and the toxic effects, when determined in the marine environment, decrease in the order Au > Zn > Ag > Cu > Ti > C 60 , but direct action of NPs cannot be ruled out. Although ecotoxicity has been assessed by a variety of techniques, it is important that a suitable standard test be developed and the European Unions's Biocidal Product Registration group is working on this, as well as a standard test for antimicrobial efficacy to determine their impact on ecological processes of surrounding non-target organisms and their transformation products under realistic scenarios.
