“…We used FTIR with ATR as a second noninvasive characterization technique requiring minimum sample preparation Journal of Nanomaterials to further understand the uptake and translocation of the NP fertilizer within the legumes [16,21]. The chemical composition of the shoot and leaves of the legumes grown from seeds presoaked in DI water, low-concentration NP fertilizer, and high-concentration NP fertilizer were investigated using an FTIR spectrometer.…”

“…The results did not suggest any significant difference in the iron content among the three different dose conditions (control, low NP concentration, and high NP concentration) for each species of legumes. Previous studies involving iron NPs in the soil matrix after seed germination have reported a dosedependent relationship between the iron NP dosage and iron content within different parts of the plant [10,16,42]. However, when applied as only seed treatment, Srivastava et al found no significant difference in iron content in spinach plant leaves with a different iron pyrite (FeS 2 ) NP dosing [12,43].…”

“…In addition to Fe NPs, iron oxide NPs have also been adopted as Fe-enriching fertilizers to replenish Fe content in plants as they are inherently nontoxic. For example, Jeyasubramanian et al showed that hematite NPs boosted the growth rate of spinach plants in a slightly acidic hydroponic system via conversion to Fe 2+ ions [16]. Ren et al reported increased physiological activity of green gram plants with iron oxide (γ-Fe 2 O 3 , maghemite) NPs.…”

There is an emerging scientific interest in the use of nanoparticle fertilizers for enhanced agricultural and bioenergy crop production to meet the growing food and energy demands of the world. The objective of designing the nanoparticle fertilizers is to effectively deliver the required nutrients for the plants without adding large quantities of fertilizer to the environment. However, most reports on nanoparticle fertilizers so far, involved the addition of nanoparticles to the hydroponic system or the soil. In this study, we report a new modified seed presoak strategy using a drop of Fe-enriching hematite nanoparticle dispersion to enhance plant growth and production in four different legume species, i.e., chickpea, green gram, black bean, and red bean. The hematite nanoparticle fertilizer drop promoted a 230-830% increase in plant growth with green gram showing the highest increase, based on our prolonged and statistically reliable growth studies. In general, we observed an increase in the survival span of plants, a twofold increase in fruit production per plant, nearly two times faster fruit production, and healthy secondgeneration plants with the nanoparticle treatment; however, there were slight species-specific variations. We used a novel multimodal material characterization approach combining three techniques, hyperspectral imaging, Fourier transform infrared spectroscopy (FTIR), and inductively coupled plasma optical emission spectroscopy (ICP-OES), to evaluate the internalization and transport of the nanoparticle fertilizer within the plants. Our results indicated that the hematite nanoparticles were transported through the roots and stems and were localized in the leaves after 10 days of growth in pots of soil. Therefore, the modified seed presoaking method using a drop of hematite nanoparticle will be highly attractive in enhancing plant growth and health, while minimizing environmental impacts.

Nanomaterials in agriculture are becoming popular due to the impressive advantages of these particles. However, their bioavailability and toxicity are key features for their massive employment. Herein, we comprehensively summarize the latest findings on the phytotoxicity of nanomaterial products based on essential metals used in plant protection. The metal nanoparticles (NPs) synthesized from essential metals belong to the most commonly manufactured types of nanomaterials since they have unique physical and chemical properties and are used in agricultural and biotechnological applications, which are discussed. The paper discusses the interactions of nanomaterials and vascular plants, which are the subject of intensive research because plants closely interact with soil, water, and atmosphere; they are also part of the food chain. Regarding the accumulation of NPs in the plant body, their quantification and localization is still very unclear and further research in this area is necessary.

“…In particular, it is known that metal oxide nanoparticles, such as copper oxide nanoparticles, exert negative effects on plants [2]. On the other hand, some NPs in suitable concentrations can enhance plant growth and could be used as nanofertilizers in agriculture to increase yields and thus decrease environmental pollution caused by classical fertilizers [3][4][5][6]. The biological effects of individual metals are more or less known, but even though combinations of xenobiotics are common in nature; their combined effects still need to be thoroughly investigated.…”

Extended AbstractCurrently, the use of nanotechnologies is in rapid expansion, which entails increasing risks of environmental contamination by nanoparticles. Many studies describe the toxic effects on humans, but little is known about the adverse environmental effects on plants. Currently, various nanoparticles are being detected in streams, wastewater and sewage due to widespread nanoparticle uses. Many toxicological studies investigate the effect of engineered NPs on various organisms, including plants [1]. In particular, it is known that metal oxide nanoparticles, such as copper oxide nanoparticles, exert negative effects on plants [2]. On the other hand, some NPs in suitable concentrations can enhance plant growth and could be used as nanofertilizers in agriculture to increase yields and thus decrease environmental pollution caused by classical fertilizers [3][4][5][6]. The biological effects of individual metals are more or less known, but even though combinations of xenobiotics are common in nature; their combined effects still need to be thoroughly investigated. Cd frequently accompanies Zn minerals in the environment [7], and due to their chemical similarity they both can be taken by plants as divalent cations. It is well-known that metals in mixtures may act independently or interact to produce additive, synergistic, or antagonistic effects [8]. We have studied the accumulation of cadmium simultaneously with metal oxide nanoparticles or with their bulk counter particles by wetland plant species (Carex vulpina).The plants were cultivated in vitro on liquid RH medium [9] supplemented with cadmium (5,62 mg/l) and ZnO (10,50,100 and 200 mg/l) or CuO (10 mg/l) in both nano and bulk form and corresponding metal salt. Metal salts were used in the concentrations that the final amount of metal contained in metal oxide was similar to the amount of metal contained in metal salt. After three weeks the plants were harvested and the amount of Cd, Zn or Cu were established by AAS in roots and leaves separately. The concentrations of photosynthetic active pigments were measured. The plants cultivated on zinc oxide accumulated the same amount of zinc independently on the form. When we compared the effect of nano and bulk zinc metal oxides on cadmium uptake there was no differences. But small amount of zinc in all forms in the medium increased the accumulation of cadmium in roots, but decreased the translocation to the leaves. On the other hand the higher concentration of zinc (200mg/l) caused decrease in concentration of cadmium in roots and increase amount of Cd ions in leaves. In the case of copper, the higher concentration of Cu was found in plants cultivated on medium supplemented by CuO in nanoform; on the other hand in these plants the smaller amount of cadmium was up taken by roots and translocated to the leaves. This study was supported by projects MYES of CR n. LD14100.
