“…Although the putative individual particle size of the nanoparticles is 25 and 70 nm, in aqueous dispersion the nanoparticles were aggregated. This occurs due to the Van der Walls forces and was also reported by Marucci et al (2019).…”

Nanotechnology presents a huge potential for plant nutrition. In this sense, foliar application of fertilizers has the advantages of delivering nutrients, reducing the environmental impact in relation to soil application. This study has investigated the effects of foliar application of CuO and CeO2 nanoparticles on soybean plants. Copper was chosen due to its importance as a nutrient for higher plants and all the processes the element participates. Cerium is the most abundant rare earth element in the Earth's crust and its abundance is not that different compared with Zn and Cu, which are much more involved in environmental investigations than Ce.During the study, it was attempted to develop an X-ray spectrometric method to trace the uptake and redistribution of nanoparticles in living plants. Even tough this was not possible, such method allowed to access the nutrional status of soybean under vivo conditions. The deposition of copper sources on leaves, such as nano and micro CuO and copper sulphate, caused damages, inducing to absence or scarce presence of platelets crystals. Shoot dry mass of plants was positively affected by the treatments, especially by the 40 nm nCuO. Copper speciation showed that the element undergoes redox reactions from Cu 1+ to Cu 2+ after 14 days of application. The nanoparticles were able to supply Cu and Ce to soybean since these elements were found in other plant tissues that were not directly exposed to the nanoparticles. However, it is not clear whether the particles are dissolved outside the leaves or taken up entirely. The use of cerium nanoparticles did not interfere in agronomic parameters such as biomass production and number of pods.

“…Furthermore, GO had no significant effect on the mortality of Asian corn borer or spider mites during a 24 h monitoring period [ 16 ]. Different concentrations of nano-CeO 2 had no significant effects on the fecundity or mortality of Myzus persicae [ 43 ]. However, GO promoted the growth and development of Asian corn borer and enhanced pupal weights [ 44 ].…”

The development and reproduction of the fall armyworm (FAW), Spodoptera frugiperda, which were reared on artificial diets containing nano-graphene oxide (GO), were determined based on age-stage, two-sex life table analysis. The results showed that GO had adverse effects on FAWs. Compared with the control, the duration of the egg stage and first, second, and sixth instar larval stages increased with increasing GO concentrations; however, the lifespan of male and female adults decreased with increasing GO concentrations. Weights of FAW pupae that were supplied with GO-amended diets increased by 0.17–15.20% compared to the control. Intrinsic growth, limited growth, and net reproductive rates of FAWs feeding on GO supplemented diets were significantly lower than the control, while mean generational periods (0.5 mg/g: 38.47; 1 mg/g: 40.38; 2 mg/g: 38.42) were significantly longer than the control. The expression of genes encoding vitellogenin (Vg) and vitellogenin receptor (VgR) expression was abnormal in female FAW adults feeding on GO-amended diets; the number of eggs laid decreased relative to the control, but Vg expression increased. In conclusion, GO prolonged the developmental period of FAWs, decreased fecundity, and led to a decline in the population size. The study provides a basis for the rational use of GO as a pesticide synergist for FAW control.

“…Another approach concerns the use of NPs made of beneficial or non-nutrient materials with stimulatory effects, e.g., enhancing germination, plant development, nutrient translocation, and antioxidant responses. 24–28 ZnO, TiO 2 , CeO 2 , and Ag NPs are produced in large quantities by industry; 29 hence several studies aimed at evaluating whether these NPs contained in commercial goods will eventually end up in the environment, thereby affecting plants. 30 One can highlight that ZnO and TiO 2 are present in sunscreen products and cosmetics, while Ag presents antimicrobial properties and is used in antimicrobial coatings and many textiles, keyboards, wound dressings, and biomedical devices.…”
