“…The N, S, Ca, Fe, Mn, and Zn concentrations of barley seeds increased compared to the control treatment while K concentration decreased with TiO2-NP treatments. On the other hand, P, and Mg, B and Cu concentrations did not affect the incensement of TiO2-NP treatments (Mattiello & Marchiol 2017). Tan et al (2017) reported that the unmodified TiO2-NPs enhanced Cu (104%) and Fe (90%); hydrophilic TiO2-NPs enhanced Fe (90%).…”

Titanium dioxide nanoparticles (TiO2-NPs) among metallic NPs are one of the most produced and consumed NPs in the world. Thus, TiO2-NPs release into the environment is inevitable. Their impact on food source cereals is still unclear. The purpose of this study was to assess the phytotoxic impacts of TiO2-NPs on growth and some mineral nutrient (zinc (Zn), iron (Fe), manganese (Mn), copper (Cu), nitrogen (N), phosphorous (P), potassium (K)) uptake of the wheat (Triticum vulgare L.) plant. The TiO2-NP suspensions at increasing concentrations (0, 5, 10, 20 and 40 mg L -1 ) were applied to wheat plant Yunus cultivar grown in hydroponic culture under controlled conditions for 21 days. The results indicate that the TiO2-NPs have not statistically significant effects on plant growth. The chlorophyll content was decreased with increasing TiO2-NP treatment, except for 5 mg L -1 TiO2-NPs treatment. The higher N (4.58%), P (0.78%), Zn (87.50 mg kg -1 ), and Cu (12.90 mg kg -1 ) concentration were recorded at 40 mg L -1 TiO2-NPs treatment. On the other hand, K concentration was decreased at 20 and 40 mg L -1 TiO2-NPs treatments. This study has shown that exposure to TiO2-NPs causes no significant phytotoxic effect on wheat.

“…The TiO 2 NPs are among the most used in the industry, and it is estimated that 0.13 to 1200 µg of TiO 2 NPs per kg of soil are incorporated each year [78]. Experimental tests to verify toxicity, transfer to ecosystems and their use as promoters of plant metabolism have also increased in number in recent years [79].…”

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.

“…The effect of ENP on plants has been investigated, and it is argued that the field of nanotechnology has excellent potential for the plant production systems (Mattiello & Marchiol, ; Prasad, Bhattacharyya, & Nguyen, ; Rastogi et al, ), with lower cost, energy, and wastes (Fraceto et al, ; Servin & White, ). In this sense, the term phytonanotechnology is used and could assist in the development of “smart” crops (Wang, Lombi, Zhao, & Kopittke, .…”

“…Especially for plant science, Mattiello and Marchiol () recognized two main groups of ENP: the carbon nanomaterial (CBNMs) and the metal‐based nanomaterials (MBNMs). In the last 3 years (2016–2018), 296 investigations were published in “Web of Science” related to the effect of ENPs on plants, but only 40 documents tie the term “nano” and “plant growth.” Other word combinations used in the search are presented in Figure .…”

Effect of engineered nanoparticles on soil biota: Do they improve the soil quality and crop production or jeopardize them?

et al. 2020

Nanoscience and nanotechnology have been shown to have the capacity to help study, manipulation,design, and synthesis of new nano-sized materials to manufacture new products with desirable features never seen before. The unique properties of materials at nanoscale opens an excellent possibility for nanotechnology to be used in soil environmental remediation, and water, and air decontamination. In crop management, nanomaterials are used to regulate the controlled release of nutrients, fertilizers, and pesticides. However, it is not only necessary to expose the positive effects by the application of the nanomaterials but also to demonstrate the impacts on soil and nontarget organisms (plants, mesofauna, macrofauna, and soil microbiota). In this context, pieces of evidence on the adverse effects of engineered nanoparticles (ENP) on the physicochemical and biological properties of soils are discussed in this paper. We have found a diversity of contradictory results. The summaries, findings, and conclusions of most of the investigations support the need to understand the biological or physicochemical transformation and transport of ENP in soil, and in the plant-organism relationship. Better understanding regarding the soil biota coupled with the ecological ENP behavior could ensure the safe use of ENP. Nanomaterials can change the physicochemical and biological properties of the soils; consequently, long-term in situ field trials are required, and meanwhile, land-application of nanomaterials should be limited to scientific experiments to fill knowledge gaps to not jeopardize the global food production or the environment and worldwide human health.
