These properties have been instrumental in addressing the drawbacks of conventional fertilizers. While NFs began to be synthesized in early 2000s, emphasis was laid on synthesis of inorganic NFs during 2010–2020. In the past decade, there have been advancements in the methods of NF synthesis, such as synthesis of metal and metal oxide NFs; synthesis of nano-composites using hydroxyapatite (HA), silica, zeolite and graphene oxide; loading of nutrients onto layered double hydroxides, and chitosan; synthesis of chelated NFs; synthesis of 2-D nano-formulations and 2-D NFs; synthesis of organic NFs using biopolymers and agricultural waste; and synthesis of nano-biofertilizers. This review primarily explores these recent advancements for targeted nutrient delivery within plants and their mechanisms of action, potential of NFs to ameliorate stress such as drought, salinity and metal toxicity to improve crop yield, and factors affecting NFs facilitated nutrient delivery. An integrated approach that uses conventional fertilizers along with NFs, tailor-made for different soil types, and use of artificial intelligence to regulate the release of fertilizers would be an ideal approach to improve plant health and increase yield, with minimal environmental impact.

Previous studies have shown that nanoparticles including Selenium can be applied to mitigate the harmful effects on various plant species. Therefore, the present study aims to evaluate the efficacy of Selenium nanoparticles (SeNPs) in mitigating salinity stress in faba bean. To investigate this, we exposed faba beans plants with three different salt concentrations (0 mM, 40 mM, and 80 mM of NaCl) then treated it with foliar sprays of SeNPs at three varying concentrations (0 ppm, 5 ppm, and 10 ppm). Under salinity stress the faba beans plants were observed to be significantly impaired in plant growth and photosynthetic activity. Furthermore, increased levels of malondialdehyde (MDA) in faba beans exposed to salinity indicated significant cellular damage. However, the application of SeNPs under salinity conditions enhanced plant height and chlorophyll content compared to the control. SeNPs also boosted the activity of key antioxidant defense enzymes, including catalase (CAT), ascorbic peroxidase (APX), and polyphenol oxidase (PPO). In addition, they decreased MDA levels and increased proline and phenol concentrations. These findings suggest that SeNPs improved plant health and vitality by mitigating oxidative stress caused by salt.

In addition, we examined gene expression in response to aluminum oxide nanoparticles (Al₂O₃NPs) and tungsten oxide particles (WO₃NPs) nanoparticles, which are known to induce stress responses in plants.
