“…In Mexico, research is also being carried out on nanoparticles that can help the development of sustainable agriculture. The use of zinc oxide nanoparticles proved to increase yield bell pepper production (Uresti-Porras et al, 2021), zinc oxide and titanium dioxide nanoparticles had exerted control against Bactericera cockerelli as a pest of tomato (Gutiérrez-Ramírez et al, 2021), and zinc oxide nanoparticles have antifungal activity towards Fusarium oxysporum-Solanum lycopersicum in tomato-fusarium pathosystem (González-Merino et al, 2021).…”

Background: The COVID-19 pandemic evidenced the fragility of the agri-food sector by affecting the food supply chains which directly depend on the health of its main actors. In this context, countries need to rethink the agricultural production models, considering environmental and human health as priorities to achieve food safety. Aim: Systematically review the state of the art regarding the role of agricultural genetic resources as a source of resilience in the face of events such as the present pandemic as a point of reflection for the identification of opportunities for the restructuring of regional agriculture sensitive to nutrition for health. Methodology: Exhaustive search and analysis of documentary information regarding the effects of COVID-19 on the agri-food sector and the role of agricultural genetic resources in the current pandemic were conducted. Then, through an analysis of the occurrence and association of the main terms addressed in the literature considered, the thematic axes were drawn to address the central discussion of the systematic review. Results: Terms co-occurrence analysis corroborated the relevance and pertinence of the topic addressed. Additionally, the importance of the conservation of agricultural genetic resources and implementation of sustainable agriculture models, as a source of resilience to pandemics, was visualized. The discussion addressed the impact of the pandemic on the Mexican agri-food sector and the restructuring of post-COVID-19 agriculture through the nation and nutrition-sensitive agriculture for health approaches. Implications: The exhaustive analysis of the relationship COVID-19-agricultural genetic resources-health in Mexico highlights the need for the generation of agricultural policies and the increase in multidisciplinary research that favors biodiversity as a source of sustainability, productivity, and health for agroecosystems and the welfare of humanity. Conclusions: A fatalistic scenario for humanity seems to be dissipating in the face of the possibilities of rethinking the economic, social, and agricultural systems from the approaches of the nation and nutrition-sensitive agriculture for health, where, through the responsible use of agricultural resources it is possible to rebuild an agri-food production system with a tendency to resilience to events such as the current pandemic caused by the COVID-19 disease.

“…It is known that zinc oxide (ZnO) is a promising multifunctional compound broadly utilized in many applications [ 1 , 2 , 3 , 4 , 5 ]. ZnO is used in optoelectronics [ 6 , 7 ], agriculture [ 8 ], wastewater treatment [ 9 , 10 , 11 ] and catalysis [ 12 , 13 ] as a vulcanization activator for rubbers, a hardener or a crosslinking agent for elastomers [ 14 , 15 ], and in the production of electrically conductive carbon materials [ 16 ]; it is also used in the cosmetics, medicine and biotechnology industries [ 17 , 18 , 19 , 20 , 21 ], including its use in the elaboration of biodegradable antibacterial packaging [ 22 , 23 ], and photovoltaic solar cells for “green” energy [ 24 , 25 ].…”

This work investigated the influence of synthesis conditions, including the use of nonionic structure-forming compounds (surfactants) with different molecular weights (400–12,600 g/mol) and various hydrophilic/hydrophobic characteristics, as well as the use of a glass substrate and hydrothermal exposure on the texture and structural properties of ZnO samples. By X-ray analysis, it was determined that the synthesis intermediate in all cases is the compound Zn5(OH)8(NO3)2∙2H2O. It was shown that thermolysis of this compound at 600 °C, regardless of the physicochemical properties of the surfactants, leads to the formation of ZnO with a wurtzite structure and spherical or oval particles. The particle size increased slightly as the molecular weight and viscosity of the surfactants grew, from 30 nm using Pluronic F-127 (MM = 12,600) to 80 nm using Pluronic L-31 (MM = 1100), PE-block-PEG (MM = 500) and PEG (MM = 400). Holding the pre-washed synthetic intermediates (Zn5(OH)8(NO3)2∙2H2O) under hydrothermal conditions resulted in the formation of hexagonal ZnO rod crystal structures of various sizes. It was shown that the largest ZnO particles (10–15 μm) were observed in a sample obtained during hydrothermal exposure using Pluronic P-123 (MM = 5800). Atomic adsorption spectroscopy performed comparative quantitative analysis of residual Zn2+ ions in the supernatant of ZnO samples with different particle sizes and shapes. It was shown that the residual amount of Zn2+ ions was higher in the case of examining ZnO samples which have spherical particles of 30–80 nm. For example, in the supernatant of a ZnO sample that had a particle size of 30 nm, the quantitative content of Zn2+ ions was 10.22 mg/L.
