“…The nanoform of CuO proved to be the most efficient in increasing the contents of Ca, Fe, or Mg, as well as allicin ( Wang et al , 2020 ). Similar results were obtained by Kohatsu et al (2021) in a study in which the foliar application of biogenic CuO NPs triggered the accumulation of K, Na, S, Ag, Cd, Cr, Cu, and Zn in lettuce leaves without causing necrosis, while CuSO 4 caused the most intense changes in the mineral element content of lettuce and caused necrotic damage. These findings indicate that nCuO is a more effective fertilizer than the other forms of Cu for lettuce cultivation ( Kohatsu et al , 2021 ).…”

Vital plant functions require at least six metals (copper, iron, molybdenum, manganese, zinc, nickel) which function as enzyme cofactors or inducers. In the past decades, the rapidly evolving nanotechnology has created nanoforms of essential metals (e.g. nZnO, nFe2O3 etc.), having a number of favourable properties over the bulk material. The effects of nanometals on plants are concentration-dependent (hormesis), but also depend on the properties of the nanometals, the plants species and the treatment conditions. This review collects studies examining plant responses to essential nanometal treatments using (multi)omics approach and emphasizes the importance of gaining a holistic view of the diversified effects. Furthermore, the review discusses the beneficial effects of essential nanometals on plants, which provides the basis for their applicability in crop production as nanopriming or nanostimulator agents, nanofertilizers etc. As by the application of essential nanometals lower environmental impact and increased yield can be achieved, nanometals support sustainable agriculture. Recent studies actively examine the utilization of green-synthetized metal nanoparticles, which perfectly fits into the environmental-friendly trend of future agriculture. There is still a long way to go before essential nanometals can be safely applied in agricultural, but it is certainly a promising direction that is timely to investigate.

“…The other two types of NP obtained were not distributed as well as CuO-NP-cel, and their size distribution could not be calculated. Other studies using green synthesis also showed similar NP shape and size; for example, Kohatsu et al [46] showed spherical shape CuO NPs synthesized using green tea extract and Dey et al [47] showed similar results for CuO NPs synthesized with Azadirachta indica. By comparing powder diffraction from bth extract, Cu-Np-bth, and Cu-Np-cel, it is evident that there is a tendency of ordering for amorphous phase because the diffraction peaks become narrower and increase in intensity, and supplementary peaks appear.…”

In the present study, the effects of copper oxide nanoparticles (CuO NPs) on bioactive compounds, the ultrastructural modifications which can occur, and elemental content of wheat were investigated. Changes in the wheat plants grown in presence or absence of CuO NPs were estimated. The application of CuO NPs decreased the amounts of chlorophylls and carotenoids and increased the amounts of polyphenols and antioxidant capacity. Ultrastructural analysis showed that the plants treated with CuO NPs were negatively affected. Soil amending completely inhibited the accumulation of seventeen elements, while K, Br, Al, and Zn were accumulated and Cl, Na, Ba, and Sr content decreased in wheat samples, regardless of the type of NPs applied. The application of chemically obtained NPs induced the most significant changes, completely blocking the assimilation of Fe, Mo, As, Sb, and Sm, and favoring much higher accumulation of Br than biogenic NPs. The decrease in chlorophylls and carotenoids is correlated with increase in antioxidant capacity, and occurs with increase of Mo, Al, Mg, K, Zn, and Ca content. The behavior of total polyphenols is correlated with Br content, and antagonist to Al behavior. From the point of view of bioactive compounds, the most affected plants were those that grew in the presence of CuO-NP-cel, while from the point of view of elementary analysis, the most affected plants were those grown in the presence of CuO-NP. By corroborating the obtained results, it was found that the CuO NPs have a negative effect on wheat plants.

“…This response depends on the dose used since CuO-NPs can induce negative responses at certain doses, while in others they can induce the opposite effect or simply have no effect [ 1 ]. This behavior, called hormesis, has been reported when metallic NPs are applied as biostimulants in cultures [ 34 ].…”

The application of metallic nanoparticles improves the yield and content of bioactive compounds in plants. The aim of the present study was to determine the effects of the foliar application of copper nanoparticles (CuO-NPs) in the yield and content of bioactive compounds in lettuce. Different concentrations of CuO-NPs (0, 0.5, 1, 2, 4, and 6 mg mL−1) were applied in lettuce. The yield, nutraceutical quality, and enzymatic activity were determined. Foliar spraying of CuO-NPs induced an increase in the biosynthesis of bioactive compounds. In addition to an increase in the activity of the enzymes superoxide dismutase (SOD) and catalase (CAT) in lettuce plants, there were no negative effects on yield. Therefore, with the application of CuO-NPs, better quality lettuces are produced for the human diet due to the higher production of bioactive compounds.
