“…Similar effects have been reported for the application of Cu NPs in tomato: foliar application increased the content of phenols, β-carotene, and vitamin C, and also increased antioxidant capacity [12]. Application via root increased the content of lycopene and vitamin C [13].…”

“…Two irrigations per week were carried out, applying 500 mL per pot or bag. The nutrient solution used by Steiner [12] was used for the nutrition of the crop. The pH of the nutrient solution was adjusted with sulfuric acid to 6.5 each time the nutrient solution was prepared.…”

“…Copper nanoparticles (Cu NPs) have been applied in different important crops, such as tomatoes [9,10] and jalapeño peppers [11], in which an increase in the main bioactive compounds was demonstrated. Specifically, foliar application of Cu NPs increased the content of biocompounds including phenols, β-carotene, and vitamin C in tomato [12]. On the other hand, the application of Cu NPs via the root system increased the content of biocompounds, such as lycopene and vitamin C, but also increased the enzymatic activity of superoxide dismutase (SOD), catalase (CAT), ascorbate peroxidase (APX), glutathione peroxidase (GPX), and phenylalanine ammonia lyase (PAL) in tomato [13].…”

Moringa oleifera Lam is a plant that has recently gained importance as a food because of its nutritional value and bioactive compound content and because practically all the organs are usable. The use of nanoparticles has appeared as an alternative to increase bioactive compounds in plants. The goal of this work was to determine if the application of copper nanoparticles would increase the content of bioactive compounds and antioxidant capacity in M. oleifera. Copper (Cu) nanoparticles were applied to the leaves at four different times throughout crop growth. The biocompounds were analyzed after the second, third, and fourth applications. The results show that application of Cu nanoparticles has a beneficial effect on the accumulation of bioactive compounds in M. oleifera leaves. In addition, the antioxidant capacity and carotenoid and chlorophyll contents in the leaves of M. oleifera increased after Cu nanoparticles application. The same effect was not observed in the fruit of M. oleifera. Here, the bioactive compound contents diminished. Therefore, the use of Cu nanoparticles can be an important alternative to improve the quality of this plant, particularly that of the leaves.

“…Foliar spraying is a practice of NPs and NMs application that substantially decreases the toxicity on plants thanks to the chemical interactions between the components of the leaf cuticle and the applied materials [97]. The NPs of Cu or CuO have been applied by foliar application with two localized applications using a suspension with 250 mg L −1 of Cu NPs to decrease the risk of toxicity [98]. This concentration of Cu NPs possibly would provide 1.25 mg L −1 of Cu 2+ .…”

Biostimulants are materials that when applied in small amounts are capable of promoting plant growth. Nanoparticles (NPs) and nanomaterials (NMs) can be considered as biostimulants since, in specific ranges of concentration, generally in small levels, they increase plant growth. Pristine NPs and NMs have a high density of surface charges capable of unspecific interactions with the surface charges of the cell walls and membranes of plant cells. In the same way, functionalized NPs and NMs, and the NPs and NMs with a corona formed after the exposition to natural fluids such as water, soil solution, or the interior of organisms, present a high density of surface charges that interact with specific charged groups in cell surfaces. The magnitude of the interaction will depend on the materials adhered to the corona, but high-density charges located in a small volume cause an intense interaction capable of disturbing the density of surface charges of cell walls and membranes. The electrostatic disturbance can have an impact on the electrical potentials of the outer and inner surfaces, as well as on the transmembrane electrical potential, modifying the activity of the integral proteins of the membranes. The extension of the cellular response can range from biostimulation to cell death and will depend on the concentration, size, and the characteristics of the corona.
