“…Both surface area and pore distribution are critical for evaluating mesoporous materials; thus, all of the N 2 adsorption-desorption isotherms of Gd 2 O 3 @MSN using BJH (Figures 4A,B) were evaluated. The samples exhibit typical type IV curves with an evident hysteresis loop, confirming its mesoporous nature (López et al, 2006;Liu et al, 2015;Philippart et al, 2017;Francesca et al, 2018;Naseem et al, 2020;Zhou et al, 2020). The BET test results also suggest that the surface area of the MSN was around 822.96 m 2 /g, making them much larger than previous versions of similar compounds (Shao et al, 2011).…”

Magnetic resonance molecular imaging can provide anatomic, functional and molecular information. However, because of the intrinsically low sensitivity of magnetic resonance imaging (MRI), high-performance MRI contrast agents are required to generate powerful image information for image diagnosis. Herein, we describe a novel T1 contrast agent with magnetic-imaging properties facilitated by the gadolinium oxide (Gd2O3) doping of mesoporous silica nanoparticles (MSN). The size, morphology, composition, MRI relaxivity (r1), surface area and pore size of these nanoparticles were evaluated following their conjugation with Gd2O3 to produce Gd2O3@MSN. This unique structure led to a significant enhancement in T1 contrast with longitudinal relaxivity (r1) as high as 51.85 ± 1.38 mM−1s−1. Gd2O3@MSN has a larger T1 relaxivity than commercial gadolinium diethylene triamine pentaacetate (Gd-DTPA), likely due to the geometrical confinement effect of silica nanoparticles. These results suggest that we could successfully prepare a novel high-performance T1 contrast agent, which may be a potential candidate for in-vivo MRI.

“…Results are so far encouraging. For instance, Naseem et al [83] studied the response of Oryza sativa in a pot experiment when fertilized with commercial urea or Si mesoporous nanoparticles (ZnAl 2 Si 10 O 24 ; 64 nm) functionalized with urea; both fertilizers were applied to the soil at the same doses. The authors observed that the release of urea from the nanocomposite was maximum and faster in the first three days and it lasted up to 336 h (14 days).…”

The Green New Deal requires a profound transformation of the agricultural sector, which will have to become more sustainable and ensure universal access to healthy food. Thus, it will be essential to introduce radical technological innovations. Nanotechnologies have the potential to produce a significant boost to the improvement of the food system. Within this context, in the next years, a strong challenge will need to be faced regarding developing new and more efficient uses of nutrients in agriculture, being the nutrient use efficiency (NUE) paramount in sustaining high crop productivity without depleting biodiversity, and altering both the natural and agricultural systems. Nutrients leaching causes environmental pollution and water eutrophication, while nutrient excess favors pest and weed widespread. Therefore, it will be mandatory to improve plant nutrition efficiency without affecting agricultural productivity and economic sustainability. A promising alternative consists of the introduction of the so-called nanomaterial enhanced fertilizers and plant growth stimulators. Such innovation includes nanotechnological solutions that can improve nutrient delivery for a more finely tuned, accurate, and saving-resources distribution of nutrients. This review provides a critical view of the latest advances in nanofertilizer research, mainly referring to nano-hydroxyapatite, silica nanoparticles, and chitosan-derived nanostructures.

“…These types of fertilizers can also be prepared by the encapsulation of nutrients within the nanomaterials [31][32][33]. Nano-fertilizers can improve the yield and quality of crops with increased nutrient usage efficiency, while lessening the production cost and thereby resulting in a sustainable agriculture [34][35][36][37][38]. The use of pesticide is a common practice in agriculture and several studies have been carried out for the advancement of effective pesticides [39][40][41][42].…”

Nanotechnology implies the scientific research, development, and manufacture, along with processing, of materials and structures on a nano scale. Presently, the contamination of metalloids and metals in the soil has gained substantial attention. The consolidation of nanomaterials and plants in ecological management has received considerable research attention because certain nanomaterials could enhance plant seed germination and entire plant growth. Conversely, when the nanomaterial concentration is not properly controlled, toxicity will definitely develop. This paper discusses the role of nanomaterials as: (1) nano-pesticides (for improving the plant resistance against the biotic stress); and (2) nano-fertilizers (for promoting the plant growth by providing vital nutrients). This review analyzes the potential usages of nanomaterials in agroecosystem. In addition, the adverse effects of nanomaterials on soil organisms are discussed. We mostly examine the beneficial effects of nanomaterials such as nano-zerovalent iron, iron oxide, titanium dioxide, nano-hydroxyapatite, carbon nanotubes, and silver- and copper-based nanomaterials. Some nanomaterials can affect the growth, survival, and reproduction of soil organisms. A change from testing/using nanomaterials in plants for developing nanomaterials depending on agricultural requirements would be an important phase in the utilization of nanomaterials in sustainable agriculture. Conversely, the transport as well as ecological toxicity of nanomaterials should be seriously examined for guaranteeing its benign usage in agriculture.
