“…Nanotechnology can provide many benefits in sustainable agriculture (Chaudhary and Misra, 2017;Kumar et al, 2017;Prasad et al, 2017), including i) control of pests and diseases using nanoformulations that enable the sustained release of pesticides, improving their effectiveness and decreasing the concentrations required to achieve the desired effects; ii) sustained release of fertilizers to increase plant growth while reducing losses in runoff and decreasing water pollution problems such as eutrophication; iii) nanoparticle-mediated transfer of genes or DNA, assisting in the development of species resistant to pests and/or diseases; iv) use of nanomaterials to develop biosensors able to detect signs of diseases and/or predators, as well as identification of lack of nutrients and water; and v) new economically viable methods for the removal of pollutants from the soil and for water treatment (Araújo et al, 2015;Duhan et al, 2017;Fraceto et al, 2016;Iavicoli et al, 2017;Mukhopadhyay, 2014;Nair et al, 2010;Rai and Ingle, 2012;Sekhon, 2014;Torney et al, 2007;Verma, 2017). Although there are various uncertainties regarding the use of nanotechnology and botanical pesticides in agriculture, cordial efforts should be made to convince the policy makers to seriously provide a market for such products by reducing many existing regulatory barriers (Amenta et al, 2015;Chandler et al, 2011;Jain et al, 2016;Sola et al, 2014b).…”

Recent decades have witnessed major growth in the use of agrochemicals worldwide,for maximizing the food production for a rapidly growing human population. However, the indiscriminate use of these substances especially the pesticides has led to the accumulation of toxic residues in food, soil, air, and water, as well as the development of resistance in pests. Moreover, pesticides affect soil enzymes, which are essential catalysts that govern soil quality. In order to meet the food security, it is necessary to produce more food, sustainably and safely, in a diminishing area of available arable land and with decreased water resources. Given this situation, there is an increased interest in the use of alternative substances to synthetic agrochemicals that present less risk to the environment and human health while increasing the food safety. Promising results have been obtained using compounds derived from aromatic plants for the control of agricultural pests. Such compounds of botanical origin can be highly effective, with multiple mechanisms of action, while at the same time having low toxicity towards nontarget organisms. However, the large-scale application of these substances for pest control is limited by their poor stability and other technological issues. In this backdrop, the present work discusses perspectives for the use of compounds of botanical origin, as well as strategies employing the encapsulation techniques that can contribute to the development of systems for use in sustainable agricultural practices.

“…This was possible due to their properties like biocompatibility [5][6][7][8], biodegradability [9][10][11], magnetic behaviour [12,13] and the possibility of easy functionalization [14,15]. Other possible uses of these nanoparticles might be in fields like catalysis [16,17], environmental remediation [18][19][20], electronics [21][22][23].…”

Functionalization of nanomaterials can enhance and modulate their properties and behaviour, enabling characteristics suitable for medical applications. Magnetite (Fe3O4) nanoparticles are one of the most popular types of nanomaterials used in this field, and many technologies being already translated in clinical practice. This article makes a summary of the surface modification and functionalization approaches presented lately in the scientific literature for improving or modulating magnetite nanoparticles for their applications in nanomedicine.

“…In the last years and decades, the development of nanosized materials has facilitated the application of remediation technologies based on highly efficient and versatile nanomaterials [36][37][38][39]. Among the possible nanoparticulate systems successfully used on a laboratory scale for soil decontamination, zero-valent iron nanoparticles (NZVI) have achieved very interesting and promising results (Table 1).…”

Zero-valent iron has been reported as a successful remediation agent for environmental issues, being extensively used in soil and groundwater remediation. The use of zero-valent nanoparticles have been arisen as a highly effective method due to the high specific surface area of zero-valent nanoparticles. Then, the development of nanosized materials in general, and the improvement of the properties of the nano-iron in particular, has facilitated their application in remediation technologies. As the result, highly efficient and versatile nanomaterials have been obtained. Among the possible nanoparticle systems, the reactivity and availability of zero-valent iron nanoparticles (NZVI) have achieved very interesting and promising results make them particularly attractive for the remediation of subsurface contaminants. In fact, a large number of laboratory and pilot studies have reported the high effectiveness of these NZVI-based technologies for the remediation of groundwater and contaminated soils. Although the results are often based on a limited contaminant target, there is a large gap between the amount of contaminants tested with NZVI at the laboratory level and those remediated at the pilot and field level. In this review, the main zero-valent iron nanoparticles and their remediation capacity are summarized, in addition to the pilot and land scale studies reported until date for each kind of nanomaterials.
