“…Iron is added in the form of soil fertilizers or chelated compounds in soil-less cultivation to facilitate iron uptake for enhanced production of agricultural and bioenergy crops. Agricultural research facilities and commercial units are investigating innovative formulations of Fe fertilizers such as the Fe micronutrient containing iron and phosphates [33][34][35]. The two major targets in designing these fertilizers are to significantly increase the plant growth or production and to minimize the addition of excess fertilizers to the soil for environmental sustainability.…”

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.

“…Their occurrence is widespread but influence on living organisms still needs to be evaluated. The relevant literature data are quite contradictory with emphasis put either on positive or negative influence of CeO 2 NPs on human health and plant development (Achari and Kowshik 2018;Dimkpa 2014;Pošćić et al 2017;Hussain et al 2019). The continuously growing production, widespread use and resistance to abundant waste treatment technologies addresses the issue of surplus nanomaterial storage and waste management.…”

The impact of cerium oxide nanoparticles, bulk cerium oxide and ionic cerium nitrate on the plant development as well as the uptake and further translocation of Cu, Mn, Zn and Fe by sugar pea (Pisum sativum L.) was investigated. Plants were cultivated in the laboratory pot experiments using the modified Hoagland solutions supplemented with cerium compounds at the 200 mg L −1 Ce level. Analysis of variance proved that cerium oxide nanoparticles significantly decreased Cu, Mn, Zn and Fe concentrations in roots and above ground parts of the pea plants. The latter ions are presumably transported via symplastic pathways and may compete with nanoparticles for similar carriers. The lowest impact on the plant growth and the metal uptake was observed under the bulk CeO 2 treatment. On the contrary, strongest interactions were observed for supplementation with ionic cerium nitrate. The highly beneficial effect of cerium oxide nanoparticles on the plant growth was not supported by this study. The latter conclusion is of particular relevance when environmental impact of cerium compounds on the waste management, municipal urban low emissions and food production is to be concerned.

“…Nanotechnology is a fast growing field that provides for the development of materials that have new dimensions, novel properties, and a broader array of applications (e.g., (Achari and Kowshik 2018;Agarwal et al 2018;Kráľová 2015a, 2017a,b;2018a,b;Prasad et al 2017a,b;Sekhon 2014;Ventola 2017). It is regarded as one of the key technologies of the 21 st century.…”

Nanotechnology providing "a new dimension" accompanied with new properties conferred to many current materials is widely used for production of a new generation of agrochemicals, in medicine it enables improved drug bioavailability, reducing undesirable side effects, minimizing non-specific uptake and specific targeting to certain target cells, while in food industry it has great importance in food protection and biofortification of food with valuable ingredients. In biobased nanoemulsions belonging to lipid nanocarriers plant oils used for oil phase, emulsifiers, biosurfactants, cosurfactants, targeting ligands on the surface of nanoemulsion (e.g., folate) or encapsulated active ingredients are of natural origin. The biocomponents of such nanoemulsions show low toxicity to living organisms, could protect encapsulated compounds for degradation, ensure their sustainable release and reduce the amount of active ingredient necessary for required effect. This chapter presents a comprehensive current overview of recent findings in the field of nanoemulsions and their utilization in agriculture and food industry, with the main emphasis on formulations encapsulating essential oils or plant extracts suitable as effective pesticide preparations as well as medicinal applications of bio-based nanoemulsions, where attention is paid to transdermal nanoemulsion formulations, the use of nanoemulsions in cancer therapy and for pulmonary and ocular drug delivery. Nanoemulsions formulated with natural emulsifiers, biosurfactants and biopolymers are presented and bio-based nanoemulsions of essential oils and their constituents as well as nanoemulsions with encapsulated vitamins, fatty acids and some bioactive compounds are discussed. Applications of nanoemulsions in edible coatings are outlined as well.
