Zinc oxide nanoparticles (ZnO-NPs): a promising nanoparticle in renovating plant science

Recent development in functional nanomaterials for sustainable and smart agricultural chemical technologies

“…Zinc oxide nanoparticles (ZnO NPs) were examined and showed promising functionalities. Recent studies have revealed the uptake, distribution and the effects of ZnO NPs in plant physiology [120]. Foliar exposure of ZnO NPs improved the growth of wheat (Triticum ) and decreased cadmium concentration in grains under simultaneous Cd and water deficient stress [121].…”

“…Similar to Ag NPs, the chemical activity of ZnO could also cause various detrimental effects in plants at high dose, which might vary with different plants as well as with the size and shape of ZnO NPs [120]. Extensive research has been conducted to overcome the antagonist effect of ZnO NPs, where low dose and duration of exposure are found to be beneficial.…”

“…Extensive research has been conducted to overcome the antagonist effect of ZnO NPs, where low dose and duration of exposure are found to be beneficial. Nevertheless, it was believed that ensuring the stability of NPs can reduce the harmful impacts of ZnO NPs in plant and simultaneously enhance their promoting efficacy [120]. In addition, safety of TiO 2 NPs was also examined [143][144][145].…”

Synthesis and characterization of novel dual-capped Zn–urea nanofertilizers and application in nutrient delivery in wheat

“…4 In contrast to these Zn forms, the advent of nanotechnology has permitted the development of novel Zn types based on the particle size, with markedly different reactivities and bioenvironmental responses. [5][6][7][8] Notably, zinc oxide nanoparticles (ZnO-NPs; #100 nm in at least one dimension) are incorporated into a variety of industrial, medical, and household products, to enhance the quality and functionality of Zn. 9 These NPs are increasingly being explored as fertilizers and pesticides to harness their novel properties in maximizing crop productivity.…”

“…9 These NPs are increasingly being explored as fertilizers and pesticides to harness their novel properties in maximizing crop productivity. 5,7,[10][11][12][13] The increasing number of studies show that Zn-based NPs can enhance plant performance when used at judicious application rates. [5][6][7][8] However, such benets are still far from being maximized for large eld-scale crop production due to the inherent and practical problems associated with micronutrients needed by plants in trace amounts, which are further complicated by the ultra-small size of nanoscale nutrients.…”
