“…For example, the bioaccumulation of silver nanoparticles (AgNPs) and aluminum oxide nanoparticles (Al 2 O 3 NPs) in roots of Lactuca sativa L. followed by their translocation to shoots has been demonstrated [5,6]. A similar behavior has been observed during the study of the uptake and translocation of lead sulfide nanoparticles (PbS NPs), iron (III) oxide nanoparticles (Fe 2 O 3 NPs) and magnetite nanoparticles (Fe 3 O 4 NPs) in Zea mays L., Triticum aestivum L. and Hordeum vulgare L., respectively [7][8][9]. Contradictory results have also been observed for the same type of metal-containing nanoparticles in different plants: titanium oxide (TiO 2 NPs) were not taken up by Coriandrum sativum L. [10], although their accumulation and translocation in tomato [11] or radish plants [12] has been reported.…”

“…Therefore, prior to the identification of extracted complexes, a different technique that allows better separation of initially fractionated species, should be applied. One of the possible options is that after SEC-ICP-MS analysis, fractions corresponding to each peak observed on the chromatograms can be collected, lyophilized and analyzed by hydrophilic interaction chromatography (HILIC) coupled to ICP-MS [7], which provides a more efficient separation of metal compounds, in terms of their polarity. Results obtained by using ICP-MS as an elemental detector provide information about type and nature of extracted metal complexes, without information about the ligands bound to the analyzed metal.…”

Due to the increasing release of metal-containing nanoparticles into the environment, the investigation of their interactions with plants has become a hot topic for many research fields. However, the obtention of reliable data requires a careful design of experimental model studies. The behavior of nanoparticles has to be comprehensively investigated; their stability in growth media, bioaccumulation and characterization of their physicochemical forms taken-up by plants, identification of the species created following their dissolution/oxidation, and finally, their localization within plant tissues. On the basis of their strong expertise, the authors present guidelines for studies of interactions between metal-containing nanoparticles and plants.

PbO x (PbO 2 and PbO, x = 1, 2) nanoparticles are emerging contaminants in dust, soil, and water due to extensive application of commercial lead products. As far as we know, the current studies are first conducted to understand the phytotoxic effects of PbO 2 (10 ± 3 nm) and PbO NPs (20 ± 5 nm) on maize (Zea mays L.) grown in hydroponic treatments. The exposure assays indicated that phytotoxic effects were dose-and size-dependent on PbO x NPs. Water uptake would be the crucial mechanism to govern the effects of PbO x on maize seed germination and root elongation, while the nanosize of particles and water transpiration processes would control maize growth and biomass production. PbO x NPs significantly influenced the macro-and micronutrients in roots and shoots of maize and significantly affected the maize growth and grain development. Our findings provide clear-cut evidence that PbO/PbO 2 NPs can bioaccumulate in maize cell organelles via apoplastic and symplastic routes from the seed and root pathways along with water uptake and transportation. The significance of this research elucidates the impacts of PbO/PbO 2 NPs on food security and indicates the threat of emerging PbO/PbO 2 NPs to human dietary health.

“…Besides plant protection, these smart NPs are extensively used to regulate the physiological process. For example, SiO 2 NPs (silicon dioxide NPs) elevates seed germination rate in Lycopersicon esculentum [ 71 , 72 ], chitosan-polymethacrylic-NPK increase biomass, nutrient uptake and antioxidant enzymes in Phaseolus vulgaris [ 73 , 74 ], Au-NPs (gold NPs) promotes seed germination, seedling growth, enzymatic activity and nutrient uptake in Zea mays [ 75 , 76 ], SiO 2 -NPs improve uptake of NPK, increase enzymatic activity and seed germination rate in Hyssopus officinalis and Z. mays [ 77 – 79 ], chitosan-CuNPs (copper NPs) enhance seed germination, activation of α-amylase, protease and activity of various antioxidant enzymes in Z. mays [ 2 , 80 , 81 ], chitosan-ZnNPs (zinc NPs) increase accumulation of zinc content and defense enzymes in Triticum durum [ 82 , 83 ], chitosan-γ-polyglutamic acid-gibberellic acid NPs promotes seed germination, root development, leaf area, hormonal efficiency, extracellular enzymes and nutrient efficiency [ 83 , 84 ], Chitosan-polymethacrylic acid-NPK NPs promotes protein content and nutrient uptake [ 74 , 85 ], ZnO-NPs (zinc oxide NPs) increase activity of catalase (60.7%), superoxide dismutase (22.8%) and nutrient acquisition [ 86 , 87 ], CeO 2 -NPs (cerium oxide NPs) enhance seed germination and vigour, enzymatic activity and nutrient uptake in Spinacia oleracea and Z. mays [ 88 – 91 ], AuNPs increase chlorophyll content and antioxidant enzyme activities in Brassica juncea [ 92 ] and TiO 2 NPs (titanium oxide NPs) enhance chlorophyll content, nutrient uptake, activity of Rubisco and antioxidant enzymes in S. oleracea and Cicer arietinum [ 89 , 93 ] (Table 1 ).…”

Conventional agriculture solely depends upon highly chemical compounds that have negatively ill-affected the health of every living being and the entire ecosystem. Thus, the smart delivery of desired components in a sustainable manner to crop plants is the primary need to maintain soil health in the upcoming years. The premature loss of growth-promoting ingredients and their extended degradation in the soil increases the demand for reliable novel techniques. In this regard, nanotechnology has offered to revolutionize the agrotechnological area that has the imminent potential over conventional agriculture and helps to reform resilient cropping systems withholding prominent food security for the ever-growing world population. Further, in-depth investigation on plant-nanoparticles interactions creates new avenues toward crop improvement via enhanced crop yield, disease resistance, and efficient nutrient utilization. The incorporation of nanomaterial with smart agrochemical activities and establishing a new framework relevant to enhance efficacy ultimately help to address the social acceptance, potential hazards, and management issues in the future. Here, we highlight the role of nanomaterial or nanocomposite as a sustainable as well stable alternative in crop protection and production. Additionally, the information on the controlled released system, role in interaction with soil and microbiome, the promising role of nanocomposite as nanopesticide, nanoherbicide, nanofertilizer, and their limitations in agrochemical activities are discussed in the present review.
