“…Judging by the data reported in the literature, there is generally a positive correlation between phenolics content and plant exposure to Ag-NPs, in our case such a relationship was revealed at higher Ag-NPs concentrations. In the present experiment we also observed an increase in phenolics content due to 40 ppm Pt-NPs application; Astafurova et al [29] found that treatment of wheat seedlings with Pt-NPs led to an increase in flavonoids contentdepending on the type of soil in which the plants grew, this increase even reached 40% compared to the control. Mirzajani et al [25] observed a significant increase in carotenoids content in rice shoots when plants were treated with 60 mg L − 1 Ag-NPs, which is consistent with our data.…”

“…Conversely, the opposite results were obtained by Feichtmeier et al [14] for barley seedlings, where fresh biomass per plant decreased with exposure to increasing concentrations of Au-NPs (3 to 10 μg mL − 1 ), but a concentration of 1 μg mL − 1 of Au-NPs in the nutrient medium had a stimulating effect on biomass. Astafurova et al [29] observed a significant increase in the weight of wheat seedlings treated with Pt-NPs in both water and soil culture; however, dry weight of shoots increased only when the plants grew in one of two soil types tested. An increase in fresh weight and dry weight of lettuce shoot was observed in our experiment due to Pt-NPs applied at higher concentration.…”

Background: Nanoparticles (NPs) serve various industrial and household purposes, and their increasing use creates an environmental hazard because of their uncontrolled release into ecosystems. An important aspect of the risk assessment of NPs is to understand their interactions with plants. The aim of this study was to examine the effect of Au (10 and 20 ppm), Ag, and Pt (20 and 40 ppm) NPs on oakleaf lettuce, with particular emphasis on plant antioxidative mechanisms. Nanoparticles were applied once on the leaves of 2-week-old lettuce seedlings, after next week laboratory analyses were performed. Results: The antioxidant potential of oakleaf lettuce seedlings sprayed with metal NPs at different concentrations was investigated. Chlorophylls, fresh and dry weight were also determined. Foliar exposure of the seedlings to metal NPs did not affect ascorbate peroxidase activity, total peroxidase activity increased after Au-NPs treatment, but decreased after applying Ag-NPs and Pt-NPs. Both concentrations of Au-NPs and Pt-NPs tested caused an increase in glutathione (GSH) content, while no NPs affected L-ascorbic acid content in the plants. Ag-NPs and Pt-NPs applied as 40 ppm solution increased total phenolics content by 17 and 15%, respectively, compared to the control. Carotenoids content increased when Ag-NPs and Au-NPs (20 and 40 ppm) and Pt-NPs (20 ppm) were applied. Plants treated with 40 ppm of Ag-NPs and Pt-NPs showed significantly higher total antioxidant capacity and higher concentration of chlorophyll a (only for Ag-NPs) than control. Pt-NPs applied as 40 ppm increased fresh weight and total dry weight of lettuce shoot. Conclusions: Results showed that the concentrations of NPs applied and various types of metal NPs had varying impact on the antioxidant status of oakleaf lettuce. Alteration of POX activity and in biosynthesis of glutathione, total phenolics, and carotenoids due to metal NPs showed that tested nanoparticles can act as stress stimuli. However, judging by the slight changes in chlorophyll concentrations and in the fresh and dry weight of the plants, and even based on the some increases in these traits after M-NPs treatment, the stress intensity was relatively low, and the plants were able to cope with its negative effects.

“…Platinum nanoparticles are another group of noble metal nanomaterials with interesting applications in plant growth. They have been reported to practically affect the growth mechanism of plants by increasing the length and weight of the plant root system [101]. The reactions of the nanoparticles are such that, if there is agglomeration, it becomes difficult for the nanoparticles to be absorbed and bio-accessibility is hampered.…”

“…The reactions of the nanoparticles are such that, if there is agglomeration, it becomes difficult for the nanoparticles to be absorbed and bio-accessibility is hampered. Astafurova et al [101] reported enhanced plant protective mechanisms due to increased flavonoids concentration resulting from nanoplatinum application. In another study of platinum nanoparticles uptake using Sinapis alba and Lepidium sativum plants, both plant species showed uptake of considerable amounts in the roots and shoots at different concentrations [102].…”

“…Assessment of safety of nanomaterials is always a difficult issue as the materials depend on a lot of factors ranging from substances or salts used, process method, biological substrates, size and structure, and reactions in medium of applications [101]. During toxicity tests, the prepared stable nanoparticles may become unstable because there is likelihood of aggregation which modifies the…”

The Role of Nanotechnology in the Fortification of Plant Nutrients and Improvement of Crop Production

et al. 2019

Nutrient deficiency in food crops is seriously affecting human health, especially those in the rural areas, and nanotechnology may become the most sustainable approach to alleviating this challenge. There are several ways of fortifying the nutrients in food such as dietary diversification, use of drugs and industrial fortification. However, the affordability and sustainability of these methods have not been completely achieved. Plants absorb nutrients from fertilizers, but most conventional fertilizers have low nutrient use and uptake efficiency. Nanofertilizers are, therefore, engineered to be target oriented and not easily lost. This review surveys the effects of the addition of macro- and nanonutrients to soil, the interaction, and the absorption capability of the plants, the environmental effect and food content of the nutrients. Most reports were obtained from recent works, and they show that plants nutrients could be enriched by applying nanoparticulate nutrients, which are easily absorbed by the plant. Although there are some toxicity issues associated with the use of nanoparticles in crop, biologically synthesized nanoparticles may be preferred for agricultural purposes. This would circumvent the concerns associated with toxicity, in addition to being pollution free. This report, therefore, offers more understanding on the application of nanotechnology in biofortification of plant nutrients and the future possibilities offered by this practice. It also highlights some of the ills associated with the introduction of nanomaterials into the soil for crop’s improvement.
