“…The present study presents a strategy for an economic and eco-friendly synthesis of ZnO nanoparticles on a large scale at relatively lower temperature as well as an in-depth physical characterisation study on the materials green synthesised. The synthesised ZnO NPs will draw our future attention in the field of nano-fertiliser [84] apart from their conventional applications. Thus, in the age of environmentfriendly development focusing on the benefits of environmental sustainability, simplicity, and low price, the present work is an important contribution to this field of research of nanomaterial.…”

Zinc oxide nanoparticles (ZnO NPs) were synthesised using Tabernaemontana divaricata flower extract (TFE) in different weight percentages by facile, eco-friendly and cost-effective green synthesis method. Formation and structure of the ZnO NPs were studied by powder XRD, FT−IR, Raman and TEM studies. The crystals formed are of hexagonal wurtzite structure with biological functional groups attached. Average crystallite size of the ZnO NPs (17.5−23.3 nm) was obtained from the analysis of powder XRD data which increased with increase of TFE amount while the estimated values of dislocation density and micro-strain exhibited an opposite behaviour. The optical (direct and indirect) energy band gap values estimated using UV–vis DRS spectral data decreased with increasing amount of TFE. The photoluminescence spectra for the ZnO NPs exhibited multiple peaks spread over the visible region with one peak in the NIR region indicating the existence of various defect levels of Zn and O. Position of these defect levels within the band gap was assigned which is significantly modulated by TFE. TFE amount-dependent peak shift and/or peak broadening were observed in the Raman spectra of the ZnO NPs which were correlated with the growing disorder in the crystals induced by the extract molecules. FESEM study showed the agglomerated NPs with quasi-spherical morphology. Particle size of the ZnO NPs was estimated from FESEM images. EDX study indicated that increased presence of TFE in ZnO decreased the oxygen content in the synthesised material. HRTEM study revealed the agglomeration of nanoparticles with single crystalline nature. Present study convincingly established that flower extract used for the green synthesis efficiently modified the structure and optical property, defect levels and morphology of the potentially useful ZnO nanoparticles.

“…Las innovaciones basadas en nanotecnología ofrecen un potencial valioso y prometedor para revivir el sector agrícola de manera sostenible en medio de la actual crisis de contaminación y seguridad alimentaria [11]. En este momento, se estima que el 15% de todos los productos en el mercado global tienen alguna manipulación incorporada con nanotecnología, como nanopartículas [12], para su uso agrícola, en donde se tiene una amplia gama de aplicaciones; otorgándole ventajas a la planta, como la absorción efectiva de macro/micronutrientes (nanofertilizantes) y una mejor permeabilidad de los compuestos activos en la lucha contra las plagas (nanopesticidas) [13] [14]. Asimismo, avances científicos han demostrado que la entrega de pesticidas y fertilizantes basada en estas biotecnologías podría reducir la huella ecológica de las actividades agrícolas, logrando aumentar la producción de cultivos mientras mejora la producción de plantas; y con ellos, los alimentos [15].…”

“…Sin embargo, no todas estas aplicaciones son siempre favorecedoras para el suelo y/o cultivo, también existen aquellas que, por lo contrario, evitan el fortalecimiento; y con ello, la optimización de la planta, afectando el crecimiento de estás. Este es el caso de las Fe NPs; sin embargo, estudios señalan que la respuesta de la planta ante este nanofertilizante, depende directamente de los niveles de las NPs en los medios de cultivo, el tiempo de exposición y las especies de plantas [13] [14].…”

In recent years, the constant challenge of finding cost-effective and sustainable alternatives has become a difficult task for all researchers worldwide. While it is true, scientific advances have been rich within this branch of green chemistry; However, there are still methodologies to be improved. This systematic review was elaborated in relation to nanotechnology and its application in agricultural field as nanofertilizers; with the aim of contributing to the community, in terms of state of the art, with the latest scientific advances in the application of nanoparticles (NPs) as new emerging technologies, in favor of the phenological development of plants and/or crops. This research could be developed from the analysis of research articles, using the PRISMA methodology, with which it was possible to collect around 200 articles; of which, considering various inclusion and exclusion criteria, among the main ones, those articles published between 2019 and 2022, 50 indexed and Q1 articles were selected. Each of these were compiled into registration matrices, characteristics and categories; Thanks to this, it was determined that 48%were published in 2022; followed by 32% found in 2021, signaling that nanotechnology will continue to advance over the years.Similarly, various methods for improving agriculture were considered in the category matrix. Finally, it was determined that, although nanofertilizers as emerging technologies contribute a large percentage in the structural development of the phenological characteristics of the plant, there are side effects; So it is important to take into account background, in order to achieve the incorporation of this new green technology in agro-industrial development.
