“…Nanofertilizers represent a new breed of fertilizers that harness advanced nanotechnology to offer an effective and sustainable approach to fertilizing crops. Their design ensures a controlled release of plant nutrients, gradually disbursing them over an extended timeframe, thereby providing a steady and essential supply of elements to [29]. This controlled-release mechanism outperforms traditional fertilizers by reducing the necessity for frequent application and the quantity of fertilizer needed.…”

The escalating challenges posed by swift population growth, global climate change, and occurrences of disease outbreaks to ensure food security necessitate innovate agricultural improvement techniques. In this intricate milieu, nanotechnology, with its remarkable advancements, emerges as a potent avenue for enhancing sustainable agricultural practices. This review underscores the current landscape of nanotechnology in agriculture, highlighting the classification and synthesis of nanomaterials. Furthermore, insightful applications of nano-based products in agriculture are meticulously elucidated in term of advantages and risks possessed. Notably, the regulatory frameworks from different countries have been addressed to ensure the safety of consumers and the environment. However, despite its myriad benefits, nanotechnology is not exempt from limitations and potential negative consequences, which are explored in the final section of this review. Keywords: nanomaterials, agriculture, nano-based products, regulatory frameworks

“…Traditionally, research on NDVs in agriculture has relied on mostly inorganic materials, such as metal and metal oxide nanoparticles for antimicrobial activity and micronutrient supplementation; , carbon dots (CDs) for photosynthesis and nutritional assimilation enhancement and resistance to biotic and abiotic stress; carbon nanotubes (CNTs) and quantum dots (QDs) for improved plant growth and biosensing; , mesoporous silica nanoparticles for delivery of pesticides and herbicides; and many of the aforementioned as vectors for gene delivery into plants . For these NDVs, size, shape, surface chemistry (which may include partial or complete organic coating), and dose have been shown to affect not only their uptake and translocation following root or foliar administration ,, but also plant growth, development, response, and toxicity. ,, …”

Nanodelivery vehicles (NDVs) are engineered nanomaterials (ENMs) that, within the agricultural sector, have been investigated for their ability to improve uptake and translocation of agrochemicals, control release, or target specific tissues or subcellular compartments. Both inorganic and organic NDVs have been studied for agrochemical delivery in the literature, but research on the latter has been slower to develop than the literature on the former. Since the two classes of nanomaterials exhibit significant differences in surface chemistry, physical deformability, and even colloidal stability, trends that apply to inorganic NDVs may not hold for organic NDVs, and vice versa. We here review the current literature on the uptake, translocation, biotransformation, and cellular and subcellular internalization of organic NDVs in plants following foliar or root administration. A background on nanomaterials and plant physiology is provided as a leveling ground for researchers in the field. Trends in uptake and translocation are examined as a function of NDV properties and compared to those reported for inorganic nanomaterials. Methods for assessing fate and transport of organic NDVs in plants (a major bottleneck in the field) are discussed. We end by identifying knowledge gaps in the literature that must be understood in order to rationally design organic NDVs for precision agrochemical nanodelivery.

Owing to the uniqueness of quantum dots (QDs) as a potential nanomaterial for agricultural application, hence in the present study, titanium dioxide quantum dots (TiO2 QDs) were successfully synthesized via sol-gel technique and the physico-chemical properties of the prepared TiO2 QDs were analyzed. Based on the results, the TiO2 QDs showed the presence of anatase phase of TiO2. TEM examination revealed spherical QDs morphology with an average size of 7.69 ± 1.22 nm. The large zeta potential value (-20.9 ± 2.3 mV) indicate greater stability of the prepared TiO2 QDs in aqueous solutions. Moreover, in this work, the application of TiO2 QDs on Hibiscus sabdariffa plants was conducted, where H. sabdariffa plants were foliar sprayed twice a week in the early morning with different concentrations of TiO2 QDs (0, 2, 5, 10, 15 and 30 ppm) to evaluate their influence on these plants in terms of morphological indexes and biochemical parameters. The results exhibited an increasing impact of the different used concentrations of TiO2 QDs on morphological indexes, such as fresh weight, dry weight, shoot length, root length, and leaf number, and physio-biochemical parameters like chlorophyll a, chlorophyll b, carotenoid contents, total pigments and total phenolic contents. Remarkably, the most prominent result was recorded at 15 ppm TiO2 QDs where plant height, total protein and enzymatic antioxidants like catalase and peroxidase were noted to increase by 47.6, 20.5, 29.5 and 38.3%, respectively compared to control. Therefore, foliar spraying with TiO2 QDs positively serves as an effective strategy for inducing optimistic effects in H. sabdariffa plants.
